The signal return is isolated from the output terminals ( & ). Note.: Non-isolated signal, referenced to the output terminals (). Note.: Isolated signal, referenced to GND-AUX. 3. Input Voltage Range Nominal input voltage range is AC 90~4V or DC ~30V. To insure proper operation, AC input should be within the pre-specified range. The wrong input will cause the power supply to operate improperly, lose the PFC function or even be damaged. Since the RCP Series have built-in active PFC circuit, there will be lower efficiency and output derating is required when operating at lower input voltage, referenced to 4. Derating. 3. Inrush Current Limiting Built-in inrush current limiting circuit. The external switch, if needed, should have a current rating exceeding the maximum inrush current. Since the inrush current limiting circuit mainly consists of thermistor and relay, after turning off the power supply, a 0 second cool down period is recommended before turning it back on. Inrush current will be much higher than the specified value if input thermistor is not allowed sufficient time to cool down. 5

Under full load output and the input voltage is within the range of 90~ 30Vac, PF>0.98; if the output is less than full load or the input voltage is higher than 30Vac, the PF value will be a little less than Output Voltage Adjustment 3.5. Adjustment of single unit Output voltage of one RCP-000 is adjustable through the potentiometer (SVR, can be found under the small circular hole on top of the unit). Please use a cross-screwdriver with isolated holder to make the adjustment Adjustment of single unit or the whole rack system Output voltage can be adjusted between 90%~0% of rated value by adding external voltage source. Please refer to Figure 3- for details. When the output is tuned to a higher voltage, please notice that the load current should be decreased accordingly. The output wattage of each unit should not exceed its rated value under any circumstances Adjustment of the whole rack system with a external 0~5Vdc source(use output voltage trimming function) ()Connect the external DC voltage source between PV (pin 4,0,9) and (pin 5) on connector, as Figure 3- shows. ()Output voltage can be adjusted between 90%~0% of rated value. The relationship between output voltage and external DC voltage source and the relationship between output current and output voltage refer to Figure 3-. (3)When the output is tuned to a higher voltage, please notice that the load current should be decreased accordingly. The output wattage of each unit should not exceed its rated value under any circumstances. PV 4,0,9 5 0~5V Figure 3- Connection for the external DC voltage source Output Voltage (%) Vout Output Current(%) V V External voltage(dc) Output Voltage(%) Figure 3-3. Fan Speed Control Built-in fan speed control circuit. The fan speed will be adjusted according to the magnitude of output load. 3. Short Circuit Protection & Over Current Protection (O.C.P.) Protection comes into effect at short circuit condition or >5% 0% of output rated current (constant current limiting mode).the PSU will automatically recover once the short circuit / over current condition is removed. 3.8 Over Voltage Protection (O.V.P.) Built-in over voltage protection circuit for each RCP-000 unit. The O.V.P. triggering points are different for different output models. Please refer to the specification sheet for details. The PSU shuts down when O.V.P. is triggered. To restart the power supply, please switch off AC input first and then wait for 0 seconds before switching it back on.

9 3.9 Over Temperature Protection (O.T.P.) And Over Temperature Alarm Built-in sets of over temperature protection circuit. When the internal temperature exceeds the threshold value, the power supply will shut down automatically (the built-in fan will still operate to cool down the PSU). You should switch off the AC input and remove all possible causes of overheating, and then let the power supply cool down to normal working temperature (needs about 0 minutes~hour) before turning it back on. When the internal temperature reaches 0, the limit of temperature alarm, the red LED on the front panel will flicker and there will be an alarm signal sent out through the PM bus interface (refer to 3.9). Even so, the power supply is still normal operating. When the internal temperature is within safe limit, there will be a "Low" signal (0~0.5V) between "T-ALARM" and "GND-AUX" on connector; When the internal temperature exceeds the threshold value, there will be a "High" signal (4.5~5.5V) between "T-ALARM" and "GND-AUX" on connector. 3.0 AC OK Signal Built-in AC input voltage detecting circuit. When AC input voltage 8Vrms, the output voltage can start to work properly and there will be a "Low" signal (0~0.5V) between "AC-OK" and "GND-AUX" on connector. When AC input voltage 5Vrms, the output voltage will be shut down and the red LED on the front panel will light up. In the mean time, there will be a "High" signal (4.5~5.5V) between "AC-OK" and "GND-AUX" on connector. 3. DC OK Signal Built-in DC output voltage detecting circuit. When DC output voltage 80% 5% of rated value, the green LED on the front panel will light up (see Figure 3-3). In the mean time, there will be a "Low" signal (0~0.5V) between "DC-OK" and "GND-AUX" on connector. When DC output voltage 80% 5% of rated value, the red LED on the front panel will be turned on. In the mean time, there will be a "High" signal (4.5~5.5V) between "DC-OK" and "GND-AUX" on connector. Figure 3-3: Front panel of RCP Fan Malfunction Protection & Alarm Signals Built-in fan malfunction protection circuit. When the DC fan stop operating (fan lock or wire broken), the output will be shutdown. In the mean time, there will be a "High" signal (4.5~5.5V) between "FAN FAIL" and "GND-AUX" on connector. Please switch off the AC source and send back to our local distributor or MEAN WELL for repair. 3.3 Remote Control Built-in remote / control circuit. Please refer to Figure 3-4 for single unit or whole rack system control. Notice that the "/" and "GND-AUX" pin on should be short connected in order to let the PSU operate properly. If it is open, the output voltage will be shut down.

When using this function, the sensing wires should either be twisted or shielded to prevent external noise interference (refer to Figure 3-5). The voltage drop across the output wires must be limited to less than 0.5V. Also heavy wires with adequate current rating should be used between / and the load. Please firmly connect the output wires to prevent them from loosing, or the power supply may be out of order. Notice: It is required to use the "Remote Sense" function to let the PSU work properly. If not, the "Local Sense" is still required that "+S" should be shorted to "" and "-S" to "" as Figure 3-. Or the output voltage will be too high, which may trigger the over voltage protection.

Insert the RCP-000 unit: Grasp the handle and push inside the rack through the rail. Pull out the RCP-000 unit: Press the clip shown in Figure 3- and pull the unit out. Clip DC OK Figure3- Location of the "clip" on RCP-000 unit 3. Parallel Operation 3.. Operation of single rack Internal parallel operation in single rack is only suitable for using the same RCP-000 unit (single unit with the same output voltage and current). Each rack (RKP-U ) have the built-in parallel connection / wiring. Once the RCP-000 unit insert in the rack then the parallel connection is done. Under parallel operation, the connection of other functions can refer to section 3.3 & Operation of three racks in parallel Parallel operation is only suitable for the same RCP-000 unit (single unit with the same output voltage and current) located in up to 3 racks. Totally 9 identical single units which operate in parallel is the maximum. Under parallel operation, the total output current should not exceed 90% of the sum of rated currents. For example: RCP x 9 connected in parallel (in 3 racks), the maximum output current should be 80A x 9 unit x 0.9 = 48A Adjust the output voltage of all the single units to the value you need and minimize the differences to less than % among one another before operating in parallel. Please parallel the racks first and then connect to the load (refer to Figure 3.8). Do not connect each rack to the load separately! The control signals DA, DB, should also be connected in parallel. (refer to Figure 3.8) Twisted wires should be used for the wiring of +S and -S. To avoid the interference, the twisted wires should not touch the load wires. (refer to Figure 3.8) A too long cable length might be with a higher amount of noise that affects rack units' proper operation in parallel. To reduce the noise, installing termination resistors, an accessory, to the unused JKs is recommended. 8

It will go back to normal ripple level once the output load is more than 0%. 3. Series Operation Higher output voltage can be acquired by connecting different racks in series. The racks (RKP-U ) connected in series should have the same single unit (RCP-000- ) in each rack. Please refer to Figure 3-9 for the reference connection method. Output current for series connection should not exceed the smallest rated current of all series connecting racks. The difference in rise times of individual rack will lead to steps/stairs like turn on. The output voltage after series connection should be less than 0Vdc [the requirement of SELV(Safety Extra Low Voltage) of IEC0950-]. It is suggested to add on external diodes (*) shown in Figure 3-9 to prevent the reverse voltage. Rating of these diodes should higher than the total amount of output voltage and current.

Through the PMBus interface, users can obtain the operation information of the power supply, including.output voltage, output current, and internal temperature of the power supply..alarm and status information. 3.Manufacturing and model information. RKP-CMU is a monitor unit particularly designed for RCP-000. Users can easily monitor operating parameters of each power supply unit by means of LCD interface or a computer PMBus Device Addressing Each RCP-000 unit should have its own device address and not the identical to communicate over the PM bus. RCP-000 uses seven bit addresses to set device address as described below. MSB LSB 0 A4 A3 A A A0 A0~A4 are used to select the PM bus address via a 5-pole DIP switch on the rear panel of RKP-U.

The value of VOUT_COMMAND is fixed and cannot be altered, while the value of VOUT_TRIM can be changed and trimmed. Take RCP-000- for example, the VOUT_COMMAND is fixed at V and the VOUT_TRIM can be trimmed to -.5, so the total output voltage is 0.5V. Adjustment range of each model shows below: Model V 4V Adjustment range 0.5 ~ 4V ~ 8V 4 ~ 5V Table PMBus monitoring notes.rkp-cmu can be used to remotely control RCP-000 by the command of "PMBus OPERATI" or connecting up the physical pins of "PMBus CTROL" and "RKP-U /" to +5V-AUX. In order to let RKP-CMU operate properly, the pin of RKP-U / connecting to +5V-AUX should be opened. Refer to Table 3- for the output control of RCP-000 shows. RKP-U / pin PMBus CTROL pin PMBus OPERATI command RCP-000 output state Connect to +5V-AUX Open 80h () Connect to +5V-AUX Connect to +5V-AUX 80h () Open Open 80h () Open Connect to +5V-AUX 80h () Don't care Don't care 00h () Table 3-.If RCP-000 is restarted, the parameters of output voltage and output current you have set will return to initial default values. 3.If PMBus is offline(such as RCP-CMU- shutdown),the parameters of OPERATI, VOUT_TRIM, and IOUT_OC_ FAULT_LIMIT you have set will return to initial default values. 4.When IOUT_OC_FAULT_LIMIT is being used to reduce the over-current point, this just can limit the output current of RCP-000 and does not trigger over-current protection. Take RCP for example, the over-current protection point is 4A when operating at 30Vac. If you set the IOUT_OC_FAULT_LIMIT to be 40A, the over-current point will be 40A. It is less than 4A, so over-current protection will not be triggered. 5.If the set value of IOUT_OC_FAULT_LIMIT is higher than Low Line Power Derating, this will trigger derated over-current protection. Take RCP for example, the over-current protection point decreases by 5% to 35.A when operating at 00Vac. If you set the IOUT_OC_FAULT_LIMIT to be 40A, this will trigger over-current protection due to the lower over-current protection point.

15 4.Notes on Operation 4. Installation Method The RKP-U should be mounted in the 9" rack first. Insert ~3 pieces of RCP-000 (with the same output voltage and current) into the RKP-U (refer to Figure 4-). Definition of module position: A is on the right, B is in the middle, and C is on the left (refer to Figure 4-). This is a power supply with built-in DC fan and please make sure the ventilation is not blocked. It is suggested that there should be no barriers within 0cm of the ventilation holes. Connect AC source to the AC input for A, B, C. module position respectively depending on the RCP-000 units assembled into the RKP-U rack.
