Transducer Technologies * Open Loop Current Transducers () Features Small package size Extended measuring range Reduced weight Low power consumption No insertion losses Eta Current Transducers Features Wide bandwidth Extended measuring range Very low power consumption Unipolar power supply 0... + 5 V Fast response time Operation principle Operation principle Eta Primary Current I P Isolated Output Voltage V OUT Primary Current I P Isolated Output Voltage V OUT The magnetic flux created by the primary current I P is concentrated in a magnetic circuit and measured in the air gap using a Hall device. The output from the Hall device is then signal conditioned to provide an exact representation of the primary current at the output. Closed Loop Current Transducers (C/L) Features Wide frequency range Good overall accuracy Fast response time Low temperature drift Excellent linearity No insertion losses Operation principle C/L Eta technology combines elements from both the Open Loop and Closed Loop principles previously defined. The result is a device that has the best balance between the features of the both operating principles. Closed Loop C Types Features High accuracy Very wide frequency range Reduced temperature drift Excellent linearity Measurement of differential currents (CD) Safety isolation (CV) Reduced loading on the primary (CV) Operation principle Primary Current I P Isolated Output Current I S Primary Current I P Isolated Output Current I S The magnetic flux created by the primary current I P is balanced by a complementary flux produced by driving a current through the secondary windings. A hall device and associated electronic circuit are used to generate the secondary (compensating) current that is an exact representation of the primary current. 6 This technology uses two toroidal cores and two secondary windings and operates on the principle of Ampere-turns compensation. For the voltage type a small (few ma) current is taken from the voltage line to be measured and is driven through the primary coil and the primary resistor. * for further information, refer the brochure "Characteristics - Applications - Calculations" or get it on www.lem.com website

Closed Loop Voltage Transducers (C/L) PRiME Current Transducers Features Measurement of high voltages Safety isolation Good overall accuracy Operation principle C/L Low temperature drift Excellent linearity Features AC measurement with wide dynamic range No magnetic saturation High overload capacity Good linearity Operation principle Accuracy independent of the position of the cable in the aperture and of xternal fields Light weight and small package Low thermal losses Primary Current I P Isolated Output Current I S A very small current limited by a series resistor is taken from the voltage to be measured and is driven through the primary coil. The magnetic flux created by the primary current I P is balanced by a complementary flux produced by driving a current through the secondary windings. A hall device and associated electronic circuit are used to generate the secondary (compensating) current that is an exact representation of the primary voltage. The primary resistor (R 1 ) can be incorporated or not in the transducer. AV 100 types Voltage Transducers Features Any kind of signal,, AC, pulsed and complex can be measured Galvanic isolation Short dynamic response for a good frequency bandwidth Fast response time Small volume needed PRiME operates on the basic Rogowski principle. Instead of a traditional wound coil, the measuring head is made of a number of sensor printed circuit boards (pcbs, each made of two separate air cored coils) mounted on a base-pcb. Each sensor PCB is connected in series so as to form two concentric loops. The induced voltage at their outputs is then integrated in order to obtain both amplitude and phase information for the current being measured. IT Current Transducers Features Very high global accuracy Low noise on the output signal Linearity <1 ppm Operation principle Low cross-over distortion High temperature stability Wide frequency range Operation principle V P Primary Current I P Isolated Output Current I S The voltage to measure (V P ) is directly applied on the primary connections through an internal resistor network and some components allowing the signal to feed an isolation amplifier. An isolated signal is recovered and conditioned to supply a current at the output, which is an exact representation of the primary voltage. IT current transducers are high accuracy, large bandwidth transducers which do not use Hall generators. The magnetic flux created by the primary current I P is compensated by a secondary current. The zero-flux detector is a symmetry detector using two wound cores connected to a square-wave generator. The secondary compensating current is an exact representation of the primary current. 7

Current Transducers The use of auto insertion equipment in the manufacturing of electronic assemblies is commonplace today. LEM produces several types of PCB mounted transducers that are designed with automated assembly in mind. These devices allow our customers to take advantage of high volume production strategies giving them the advantage necessary to remain competitive. Designed for automated assembly In addition to the benefit of automated assembly that an integrated primary bus bar offers, it also has an important impact on the performance of the product. By locating the primary conductor in exactly the right place in relation to the secondary winding, we maximize the primary to secondary coupling of the transducer. This gives transducers their excellent high frequency properties. Smallest Packages The current transducer, weighing only 10 g, requires only a small area on the printed circuit board, and is optimally suited for automated production lines. 10 5 4 1 2 3 8 7 23 22 6 27 Selection parameter 1: Supply voltage Most current transducers are still designed for bipolar supply voltages. This means that the integrated electronics are supplied with both positive and negative potentials with reference to ground (0V). V C = 0, ±12V; 0, ±15V; 0, ±24V; etc. The new generations of ASIC based transducers operate on a single unipolar supply with reference to ground (0V). V C = 0... +5 V This option allows the user to save cost by removing the need for dual supply. It is important when choosing between the alternative technologies to consider the current requirements that transducers place on their power supplies. Typically, we have the following current based on the technology employed: Open Loop Closed Loop Eta C Type IT Type AV 100 Type PRiME 20 ma 10 ma + compensation current 16 ma 40 ma 90-200 ma + compensation current 50 ma + secondary output current 30 ma 8

Current Transducers The amount of board space a component occupies is an important design criteria. LEM has developed a series of transducers that require only a small area on the circuit board. They use if possible, the same housing or similar packaging for different current ranges. For the user, this simplifies the development of a complete product series covering several power ranges. Optimum use of space The compact design of the ASIC-based LTS, LTSR, LAS and new HAIS and HXS series transducers, enable users to take advantage of the intrinsic benefits of isolated Hall effect-based current measurement - high accuracy, fast response, and, wide bandwidth - without the usual tradeoff in PCB real estate. Multiple shapes and sizes Use of ASIC based transducers, LTS series, in an inverter for control and protection. 21 26 9 24 12 15 16 28 13 17 19 1 2 3 25 18 20 Selection parameter 2: Frequency response The frequency response for LEM transducers is primarily dependent on the type of transducer, i.e. closed or open loop, etc., since within each type there are a number of key factors which fundamentally affect the transducers bandwidth. For open loop transducers, the core geometry, the number and thickness of the laminations, and the specific core material have a direct impact on bandwidth. In the case of closed loop, Eta and IT-type, (and to a lesser extent, C-type) the coupling between the primary and secondary - which is affected by the particular core geometry and construction - is the determining factor in transducer bandwidth. 10 When for the AV 100 Type and PRiME, it's a question of electronic limitation. In general bandwidth is as follows: Open Loop to 25/50 khz * ETA and IT Type to 100 khz (-1dB) Closed Loop to 200 khz (-1dB) C Type to 500 khz (-3dB) AV 100 Type to 13 khz (-3dB) PRiME AC 10 Hz to 6 khz (-3dB) (typically but can go up to several khz) * Note: Small signal bandwidth to avoid excessive core heating at high frequency.

Current Transducers Quality is requested by everyone and it is quite justified. The levels required by customers can be different according to the applications. This quality has to be reached but also maintained in the time and constantly improved as well as for products than for services. The different LEM design and production centers around the world are either ISO TS 16949, and/or ISO 9001 and/or ISO 14001 certified. LEM quality Several quality tools have been implemented in LEM to assess and analyze its performances to be able to take the necessary actions to remain a responsive player in the market. Among which the most representatives are : - DPT FMEA (Design Process Tool & Failure Mode Effect Analysis) - Control Plan - Cpk R&R (Capability for Processes & measurement systems) - QOS 8D (Quality Operating System Eight Disciplines) - IPQ (Interactive Purchase Questionnaire). In addition to these quality programs and since 2002, LEM embraces Six Sigma as its methodology in pursuit of business excellence. The main goal is to create an environment in which anything less than Six Sigma quality is unacceptable.

Some are dependent of the transducer itself when the others are linked to the application. These criteria are the followings: Clearance distance Creepage distance Pollution degree (of the application) Overvoltage category (of the application) 14 Comparative Tracking Index (CTI linked to the kind of material used for the transducer case) leading to a classification over different Insulating Material groups Simple or Reinforced isolation need. LEM transducers follow this thought process for their designs. For PCB mounting transducers, the customer PCB tracks layout has to be taken into account to find the possible working voltage. Indeed, the clearance and creepage distances can be different according to the customer PCB layout.

Current Transducers for Automation The key feature of this specific range of products is to provide outputs suited for interface to process control systems. Outputs provide an instantaneous, RMS or True RMS signal and could be a voltage (10 V or 5 V) or current (4-20 ma). That allows a direct interface with a PLC, meter, or other instruments. Transducers are available with solid core or split core package and can be panel fixed or DIN rail mounted. Multiple applications These transducers are particularly well suited for the following applications: - AC or motor load control (pump, conveyor, fan, machine tool, ) - Metering - Remote monitoring - Heater load control - Battery current monitoring - Light control Automated controlling of pumps Multiple electrical and mechanical configurations with a variety of output signals 79 77 80 81 76 78 Selection parameter 7: Output signal LEM transducers are available with different output signals, depending on the operation principle and the application. Closed Loop transducers generally provide a current output, proportional to the primary signal. The user can obtain a voltage signal by defining a burden resistor within the limits specified in the datasheet. Open Loop, Eta,CT type and PRiME transducers directly provide an amplified voltage signal proportional to the primary current. In the case of single supply voltage, the output signal varies around a nonzero reference. The process control series offers specific output signals suited to interface with PLCs, controllers, meters, and other instrumentation. The following output options are available: - Instantaneous voltage or current (4-20 ma) - True RMS voltage or current (4-20 ma) 20

Voltage Transducers A wide selection of LEM solutions is available for galvanically isolated voltage measurement, at various levels of performance. LEM currently offers two different options for voltage measurement: User specified primary resistor: The user connects a primary resistor in series with the transducer. The value of the primary resistor R 1 is selected according to the voltage to be measured. This approach allows for maximum flexibility Integrated primary resistor: The integrated primary resistor R 1 predefines the nominal measuring voltage of the transducer. LEM offers a wide selection of nominal voltage levels to cover a variety of applications. Selectable voltage measurements Many applications require the assessment of electric power, with the combined measurement of LEM voltage and current transducers. Users can control a variety of systems, including the lighting of airport runways. Together with current transducers, voltage transducers are used for controlling the brightness of the lights on runways. Multiple package configurations 85 87 82 83 84 Selection parameter 8: Design standards LEM transducers are designed and tested according to recognized worldwide standards. Our range of industrial transducers comply with the following requirements: EN 50178 is our standard of reference for electrical, environmental and mechanical parameters.

Voltage Transducers IGBT commutation generates voltage variations with high dv/dt levels. These fluctuations may induce errors on the output signal of voltage transducers. LEM has developed special versions of transducers with a screen between the primary and the secondary circuit, significantly reducing the error generated by these perturbations. Addressing EMC The screen is a standard feature on several series of voltage transducers (CV3, AV 100, LV 200-AW/2), and is available as an option on LV 100 series. Multiple package configurations Custom-tailored solutions for current and voltage measurement. 90 86 88 89 88 Selection parameter 9: Measuring Accuracy Accuracy is a fundamental parameter in electrical systems. Selecting the right transducer is often a trade-off between several parameters: accuracy, frequency response, weight, dimensions, costs... The measuring accuracy for LEM transducers depends primarily on the operation principle. Open Loop transducers are calibrated during the manufacturing process and typically provide an accuracy better than 2 % of the nominal range at 25 C. For additional offset and gain drift parameter, please refer to individual datasheets. New ASIC based Open Loop and Eta transducers are being developed to provide improvement in gain and offset drift over traditional Open Loop transducers. 24 Closed Loop current and voltage transducers provide excellent accuracy at 25 C, in general below 1 % of the nominal range, and a reduced error over the specified temperature range, thanks to their balanced flux operation. IT and CT types are high performance transducers with exceptional accuracy level over their operating temperature range. Individual datasheets provide all relevant information to precisely calculate the overall accuracy of a given transducer in a specific application.
