For local sense use only, can't be connected directly to the load..functions. Input Voltage Range Nominal input voltage range is AC 9~64V or DC ~V. 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 (<VAC).. 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 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.. Output Power Single Unit RCP-- : W (V / 6A) RCP--4 : 96W (4V / 4A) RCP--48 : 8W (48V / A) Whole System RCP-KU ¼- : 6W (V / 8A) RCP-KU ¼-4 : 88W (4V / A) RCP-KU ¼-48 : 4W (48V / 6A).4 Power Factor Correction (PFC) Built-in active power factor correction (PFC) function. Under full load output and the input voltage is within the range of 9~Vac, PF>.96; if the output is less than full load or the input voltage is higher than Vac, the PF value will be a little less than.96.. Output Voltage Adjustment.. Adjustment of single unit Output voltage of one RCP- 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 difference of each unit in the same rack should be maintained within Ó%, or the effectiveness of current sharing might be influenced. Output voltage can be adjusted between 9%~% of rated value by adding external resistors (R and R). Please refer to Figure -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.

.6 Fan Speed Control Built-in fan speed control circuit. The fan speed will be adjusted according to the magnitude of output load.. Short Circuit Protection & Over Current Protection (O.C.P.) Protection comes into effect at short circuit condition or >% Ó% of output rated current (constant current limiting mode). The PSU will automatically recover once the short circuit / over current condition is removed..8 Over Voltage Protection (O.V.P.) Built-in over voltage protection circuit for each RCP- 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 seconds before switching it back on..9 Over Temperature Protection (O.T.P.) 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 minutes~hour) before turning it back on. If the internal temperature is under the threshold value, there will be a "Low" signal (~.V) between "T-ALARM" and "" on ; if the internal temperature exceeds the threshold value, there will be a "High" signal (4.~.V) between "T-ALARM" and "" on connector.. Over Temperature Alarm Every RCP- single unit has a detecting circuit to sense its internal temperature. The value of internal temperature can only be read through the I C interface: when the internal temperature of RCP- is higher than 6 J Ó J, there will be an alarm signal sent out through the I C interface.. AC OK Signal Built-in AC input voltage detecting circuit. When AC input voltage Ù 8V Ó4V, the output voltage can start to work properly and the "AC OK" LED on the front panel will light up (see Figure -). In the mean time, there will be a "Low" signal (~.V) between "AC-OK" and "" on connector. When AC input voltage Ø 8V Ó4V, the output voltage will be shut down and the "AC OK" LED on the front panel will be turned off. In the mean time, there will be a "High" signal (4.~.V) between "AC-OK" and "" on connector.. DC OK Signal Built-in DC output voltage detecting circuit. When DC output voltage Ù 8% Ó% of rated value, the "DC OK" LED on the front panel will light up (see Figure -). In the mean time, there will be a "Low" signal (~.V) between "DC-OK" and "" on connector. When DC output voltage Ø 8% Ó% of rated value, the "DC OK" LED on the front panel will be turned off. In the mean time, there will be a "High" signal (4.~.V) between "DC-OK" and "" on connector. Figure -: Front panel of RCP- DC OK AC OK. Fan Malfunction Protection Built-in fan malfunction protection circuit. When the DC fan stop operating (fan lock or wire broken), the output will be shut down. Please switch off the AC source and send back to our local distributor or MEAN WELL for repair..4 Remote Control Built-in remote ON/OFF control circuit. Please refer to Figure - for single unit or whole rack control. Notice that the "ON/OFF" and "" 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. RCP-U ON/OFF A ON/OFF B ON/OFF C Whole rack ON/OFF 8 SW RCP-U ON/OFF A ON/OFF B ON/OFF C Single unit ON/OFF 8 SW Between "ON/OFF" and "" on SW Open SW Short Output Status OFF ON Figure -: Connection for remote ON/OFF control operation. Remote Sense Built-in remote sense circuit that can compensate voltage drop up to.v. When using this function, the sensing wires should either be twisted or shielded to prevent external noise interference. (refer to Figure -4) The voltage drop across the output wires must be limited to less than.v. 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 "" to "" as Figure -. Or the output voltage will be too high which may trigger the over voltage protection. RCP-U () +S () LOAD Twisted wires Figure -4: Connection for using the "Remote Sense" function RCP-U +S Figure -: Connection for using the "Local Sense" function.6 Hotwap Operation Built-in "Oring diode" in every RCP- unit that the single unit can be hot-swapped without turning off the AC source provide to the whole rack system. Insert the RCP- unit: grasp the handle and push inside the rack through the rail. Pull out the RCP- unit: press the clip shown in Figure -6 and pull the unit out. DC OK AC OK Clip Figure -6: Location of the "clip" on RCP- unit. Parallel Operation.. Operation of single rack Internal parallel operation in single rack is only suitable for using the same RCP- unit (single unit with the same output voltage and current). Each rack (RCP-U ¼) have the built-in parallel connection / wiring. Once the RCP- unit insert in the rack then the parallel connection is done. Under parallel operation, the connection of other functions can refer to section.4 &.... Operation of three racks in parallel Parallel operation is only suitable for the same RCP- unit (single unit with the same output voltage and current) located in up to racks. Totally 8 identical single units operate in parallel is the maximum. Under parallel operation, the total output current should not exceed 9% of the sum of rated currents. For example: RCP--4 Ñ8 connected in parallel (in racks), the maximum output current should be 4A Ñ 8 unit Ñ.9 = 88A 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 paralleling the racks first and then connect to the load (refer to Figure.). Do not connect each rack to the load separately! The control signals CS, +S, should also be connected in parallel. (refer to Figure.) Twisted wires should be used for the wiring of +S and. To avoid the interference, the twisted wires should not touch the load wires. (refer to Figure.) 8

It will go back to normal ripple level once the output load is more than %..8 Series Operation Higher output voltage can be acquired by connecting different racks in series. The racks (RCP-U ¼) connected in series should have the same single unit (RCP-- ¼) in each rack. Please refer to Figure -8 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 6Vdc [the requirement of SELV(Safety Extra Low Voltage) of IEC69-]. It is suggested to add on external diodes shown in Figure -8 to prevent the reverse voltage. Rating of these diodes should higher than the total amount of output voltage and current.
