RCP-2000,RKP-1U Instruction Manual
◎Risk of electrical shock and energy hazard. All kinds of failure should be examined by a qualified technician. Please do not remove
the case of the RCP-2000 or RKP-1U by yourself!
leakage current of the rack system (including 3 * RCP-2000 units and 1 RKP-1U rack) is less than 3.5mA.
of the rated value.
1.1 Introduction
1.2 Features
1.3 Order Information
◎Please do not change any component on the RCP-2000 series by yourself or make any kind of modification on it.
◎Please do not install the RCP-2000 series in places with high moisture, high ambient temperature or under direct sunlight.
◎The rated input voltage / frequency are 100~240VAC and 50/60 Hz. Please don't feed in AC power that is greater or less than 10%
◎Safety protection level of this unit is class I, The grounding wire should be firmly fixed at the "FG" terminal ( ) of the rack. The total
◎44 mm low profile, suitable for standard 1U rack applications.
RCP series are rack-mounted power supplies that provide power source for telecom equipments, servers, or monitoring equipments
in the 19" racks.
◎Universal AC input / Full range.
◎Built-in active PFC function, PF>0.98.
◎Protections: short circuit / overload / over voltage / over temperature.
◎Active current sharing up to 6000W (3 units) in one 19" rack; up to 3 racks (9units maximum) can be connected in parallel.
◎Remote control for single RCP-2000 unit.
◎Built-in remote sense function.
◎Output voltage can be trimmed between 90~110% rated output voltage.

3.Functions
3.1 Input Voltage Range
3.2 Inrush Current Limiting
◎Nominal input voltage range is AC 90~264V or DC 127~370V.
◎To insure proper operation, AC input should be within the pre-specified range. A 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 4.2 Derating.
◎Built-in inrush current limiting circuit.
◎An 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 10 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.

3.5 Output Voltage Adjustment
3.5.1 Adjustment of single unit
Output voltage of one RCP-2000 is adjustable through the potentiometer (SVR1, 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.
3.5.2 Adjustment of single unit or the whole rack system
3.5.3 Adjustment of the whole rack system with a external 0~5Vdc source(using output voltage trimming function)
◎When the output is tuned to a higher voltage, please notice that the load current should be decreased accordingly. The
◎Output voltage can be adjusted between 90%~110% of the rated value by adding external voltage source. Please refer to
Figure 3-1 for details.
output wattage of each unit should not exceed its rated value under any circumstances.
DC voltage source and the characteristics of output current and output voltage refer to Figure 3-2.

3.8 Over Voltage Protection (O.V.P.)
◎Built-in fan speed control circuit. The fan speed will be adjusted according to the magnitude of output load.
◎Protection comes into effect at short circuit condition or >115%±10% of output rated current (constant current limiting mode).The
◎Built-in over voltage protection circuit for each RCP-2000 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 the unit and then wait for 10 seconds
before switching it back on.
PSU will automatically recover once the short circuit / over current condition is removed.
3.4 Power Factor Correction (PFC)

PF value will be greater than 0.98; if the output is less than full load or the input voltage is higher than 230Vac, the PF value will
be slightly less than 0.98.

3.19.1 PMBus Device Addressing

◎Each RCP-2000 unit should have their unique and own device address to communicate over the PMbus. 7-bit address
setting pins are used to assign a device address for a RCP-2000 unit, as the description shows below .
A0~A4, five of the bits, can be set via a 5-pole DIP switch on the rear panel of a rack unit. The "ON" position represents
logic "0" while the "OFF" position represents logic "1".
There are 32 different addresses available to be assigned by the DIP switch. The switch settings show as below.

◎RCP-2000 is compliant with PMBus Rev.1.1, the maximum communication speed is 100KHz, which allows up to 9 units to
be identified and controlled over the bus.

◎When RCP-2000 units are operating in high ambient temperature or at a low AC input voltage, these units will de-rate their output
current automatically to protec themselves, as shown in Figure 4-2.
◎EMI radiation test is greatly affected by wiring, attaching an EMI suppressor(ferrite core) to the AC cable as close as possible
to the AC inlet to reduce noise is recommend. There are suggested components for reducing EMI radiation interference including
TDK HF70RU26*29*13S, NEC ESD-SR-250H, and EROCORE FH29.7*13*25.9.
◎Three years of global warranty is provided for RCP-2000 series/ RKP-1U under normal operation. Please do not change any
component or modify the unit by yourself or MEAN WELL may reserve the right not to provide the complete warranty service.
