Power Supply, Primary Switch Mode, Narrow Design -PS-100-240AC/24/2 POWER provides: Extra narrow widths of 22.5 and 45 mm (0.886 and 1.772 in.) Global use due to a wide range input A high level of operational safety in complex global networks Reliable start up of heavy loads due to POWER BOOST The reliability of a power supply determines the availability of individual components in a system and whether complex systems can function safely. The globalization of markets increases the demands placed on the power supply. A wide range input and a high level of availability are required. These requirements are met by POWER. 1. Brief Description POWER is the extra narrow power supply, which is available in widths of 22.5 and 45 mm (0.886 and 1.772 in.). In addition to a 24 V version with output currents of 0.65 A and 2 A, special voltages are also available with 5 V/3 A and /- 15 V/1 A. The POWER BOOST - a power reserve of up to 100% - ensures a reliable start of difficult loads. The high level of operational safety is also ensured in complex global networks. POWER also operates in applications where static voltage dips, transient power supply failures or phase failure are common. arge capacitors ensure mains buffering of more than 20 ms at full load. 2. Area of Application POWER can be used globally due to the consistent conversion of a wide range input. In this way, your entire system can be tested at any production location in the world and can be delivered to any location in the world without faulty switching of the input voltage. This reduces storage costs and logistical effort. An international approval package including U 60950 for IT equipment and U 508 for industrial control equipment enables the device to be used globally. Headquarters: Phoenix Contact GmbH & Co.

Safety and Warning Instructions Installation and startup must only be carried out by qualified personnel. The relevant country-specific regulations (e.g., VDE, DIN) must also be observed. Before startup it is particularly important to ensure that: The line has been connected correctly and protection is provided against electric shock. The device can be switched off outside the power supply according to EN 60950 regulations (e.g., by the line protection on the primary side). All supply lines have sufficient fuse protection and are the correct size. All output cables are the correct size for the maximum device output current or have separate fuse protection. Sufficient convection is ensured. POWER is a built-in device. After installation the terminal area must be covered to provide sufficient protection against unauthorized access to live parts. This is ensured by installing the device in the control cabinet or distributor box. The device contains dangerous live components and high levels of stored energy. To ensure safe operation of the device and that all functions can be used, please read these instructions carefully. Caution: Never carry out work when the power is turned on, this is highly dangerous. PHOENIX CONTACT page 4 of 8

Power Supply, Primary Switch Mode, Narrow Design -PS-100-240AC/24/2 6.4. Output (2, Figure 9) The 24 V connection is made using the "" and "" screw connections on the screw-cage connection 2. The output voltage set upon delivery is 24 V. The output voltage can be adjusted from 22.5 to 28.5 V on the potentiometer 4. Protecting the Secondary Side: The device is electronic short-circuit-proof and idlingproof. In the event of an error, the output voltage is limited to a maximum of 33 V. It should be ensured that all output cables are the correct size for the maximum output current or have separate fuse protection. The secondary side cables should have large cross sections to keep voltage drops on the cables to a minimum. 24 V 20 ma Output 24V Active signal output (3, Figure 10) The 24 V signal is between the " " and "" connection terminals and can be loaded with 20 ma maximum. This signal output indicates that the output voltage has fallen below 21.5 V when "active high" changes to "low". The signal is isolated from the power output. This ensures that a separate supply does not enter from devices connected in parallel. The 24 V signal can be connected directly to the logic input for evaluation. Figure 10 ED The green ED enables local function evaluation in the control cabinet. ED on Normal operation of the power supply ED off a) The output voltage is 21.5 V. There is a secondary load short circuit or overload outside the POWER BOOST area. b) No AC supply voltage is present or there is a device fault. 7. Installation 7.1. Output Characteristic Curve The device can supply up to 4 A at 24 V output voltage for a few minutes (P out = 96 W). With high loads, the working point demonstrates the U/I characteristic curve shown in Figure 11. The output current is limited to I BOOST. The secondary voltage is reduced until the short circuit on the secondary side is removed. The U/I characteristic curve ensures that both heavy capacitive loads and devices with / converters can be supplied by POWER in the input circuit without any problems. Connected fuses are reliably tripped. The selectivity in your system configuration is ensured at all times.

Power Supply, Primary Switch Mode, Narrow Design -PS-100-240AC/24/2 7.2. Temperature Response At an ambient temperature of up to 60 C (140 F) the device can supply an nominal current of 2 A. POWER BOOST is available for a few minutes. The output power must be decreased by 5% per Kelvin temperature increase for ambient temperatures over 60 C (140 F). At ambient temperatures over 70 C (158 F) or in the event of a thermal overload, the device switches off to protect itself. The device switches on again once it has cooled down. Output current [A] 4 2 0 0 U OUT = 24 V POWER BOOST 20 40 60 Ambient temperature [ C] 7.3. Parallel Operation Devices of the same type can be connected in parallel to increase both redundancy and power. The default setting does not have to be adjusted. If the output voltage is adjusted, an even current distribution can be ensured by precisely setting all power supplies that are operated in parallel to the same output voltage. To ensure symmetrical current distribution we recommend that all cable connections from the power supply to the DIN rail are the same length and have the same cross section. Depending on the system, for parallel connection of more than two power supplies a protective circuit should be installed at each individual device output (e.g., decoupling diode). This means that in the event of a secondary device fault high return currents are avoided. Figure 12 7.4. Redundancy Operation Redundant connections are designed for supplying systems, which place particularly high requirements on operational safety. If a fault occurs in the primary circuit of device no. 1, device no. 2 automatically takes over the complete power supply without interruption and vice versa. For this purpose, the power supplies to be connected in parallel must be large enough that the total current requirements of all loads can be completely covered by one power supply. External decoupling diodes or fuse are required for 100% redundancy. 7.5. Power Increase The output current can be increased to n x I N where n is the number of devices connected in parallel. The parallel connection for power increase can be used to extend existing systems. A parallel connection is recommended if the power supply does not cover the current consumption of the most powerful load. Otherwise, the loads should be divided over independent individual devices. A maximum of five devices can be connected in parallel. 24 V/2 A 24 V/2 A Σ = 2 A 24 V/2 A 24 V/2 A Σ = 4 A Figure 13 Figure 14 PHOENIX CONTACT 15.04.02 TNR: 5107490-04 http://www.phoenixcontact.com PHOENIX CONTACT page 8 of 8
