MEAN WELL RCP-2000-12 is a rack-mount front-end AC/DC power supply module with a 12 V output rated at 100 A and 1200 W. It uses active PFC and a controlled DC fan, with remote sensing, voltage programming and hot-swap isolation for the matching rack system. This version includes PMBus communication.

Model-Specific DC Output
| Rated output voltage |
12 V. |
| Rated output current |
100 A; load range 0–100 A. |
| Rated output power |
1200 W. |
| Ripple and noise, maximum |
150 mVp-p. |
| Built-in voltage adjustment |
10.5–14 V. |
| Voltage tolerance |
±2.0%; includes set-up, line and load regulation. |
| Line / load regulation |
±1.0% / ±1.0%. |
| Typical efficiency |
86% at 230 VAC and rated load. |
The current and power limits apply together. Voltage adjustment or programming does not increase the permitted continuous output power; apply the input and temperature derating limits.
Input, Timing and Low-Line Limits
| Input voltage |
90–264 VAC or 250–320 VDC. |
| AC frequency |
47–63 Hz. |
| Typical AC input current |
13 A at 115 VAC; 7 A at 230 VAC. |
| Input power factor |
Built-in active PFC; typical PF 0.98 at 230 VAC and full load. |
| Cold-start inrush current |
50 A. |
| Leakage current |
Less than 1.1 mA at 230 VAC. |
| Set-up / rise time |
1500 / 60 ms at 230 VAC, full load. |
| Typical hold-up time |
16 ms at 230 VAC and 75% load; 10 ms at 230 VAC and full load. |
Full rated output is available on the 180–264 VAC plateau; lower input voltages require derating.
Printed low-line limits for this voltage model: 115 VAC: 1140 W maximum and 95 A maximum; 100 VAC: 1080 W maximum and 90 A maximum; 90 VAC: 960 W maximum and 80 A maximum. Apply these together with the temperature curve.
The catalogue specifies withstand capability for a 300 VAC surge lasting 5 seconds; this is not a continuous input-voltage rating.
For operation at 320–370 VDC, contact the manufacturer; this range is outside the standard 250–320 VDC input specification.
Protection and Cooling
| Short-circuit / overload protection |
105–125% of rated output power; constant-current limiting followed by output shutdown after 5 seconds; re-power to recover. |
| Overvoltage protection |
14.7–17.5 V; output shutdown, re-power to recover. |
| Overtemperature protection |
Output shutdown; automatic recovery after the temperature falls. |
| Cooling |
Built-in DC fan with fan-speed control. Keep the fan inlet and connector-end exhaust unobstructed. |
| Hot-swap isolation |
Built-in OR-ing FET supports hot-swap operation in the compatible rack system. |
Temperature and Environmental Limits
| Working temperature |
-35°C to 70°C; subject to the load curve. |
| Working humidity |
20–90% RH, non-condensing. |
| Storage temperature / humidity |
-40°C to +85°C; 10–95% RH, non-condensing. |
| Temperature coefficient |
±0.03%/°C from 0°C to +50°C. |
| Vibration |
10–500 Hz, 2 G, 10-minute cycle; 60 minutes each along X, Y and Z. |
For horizontal installation, 100% load is shown from -35°C to +50°C at 230 VAC; the -35°C to below -25°C region is restricted to 230 VAC. Derate to 50% at +70°C.
Above 2000 m altitude, reduce the allowed ambient temperature by 5°C per 1000 m for these fan-cooled supplies. The general altitude derating note does not replace installation or safety limits.
The efficiency-versus-load graph is for the 48 V model at 230 VAC; the model-specific typical efficiency is listed in the output table.
Remote Sense, Voltage Programming and PMBus
| Remote sense |
Compensation up to 0.5 V. Use a twisted pair from +S pin 14 and -S pin 15 to the load. For local sensing link these to +V signal pin 10 and -V signal pin 9 respectively. |
| Remote ON/OFF |
Short pin 17 to +5V-AUX pin 29 for ON; open for OFF. |
| External voltage programming |
90–110% of nominal voltage; PV pin 11 referenced to -V signal pin 9. |
| Communication |
PMBus Rev.1.1, maximum 100 kHz; SDA pin 23 and SCL pin 24. |
The PV graph shows 100% output at 0–0.5 V control, 90% at 0.5–1.5 V, increasing from 90% at 1.5 V through 100% at 3 V to 110% at 4.5 V, and 110% at 4.5–5 V. Keep the operating point within the model current and power limits.
In multi-rack parallel operation at light load, ripple may exceed the single-unit specification; the specified ripple level is restored above 10% output load. Use DA/DB and address wiring as specified for the compatible rack system.
Connector and Signal Assignments
CN501 is Positronic PCIM34W13M400A1; mating reference PCIM34W13F400A1. Pins 1–4: +V; 5–8: -V; 9: -V signal; 10: +V signal; 11: PV; 12/13: DA/DB; 14/15: +S/-S; 16/18/19/20/21: A0/A1/A2/A3/A4; 17: remote ON/OFF; 22: N.C.; 23/24: SDA/SCL; 25: AC OK; 26: DC OK; 27: T-Alarm; 28: fan fail; 29: 5V-AUX; 30: 12V-AUX; 31: GND-AUX; 32: FG; 33: AC/L; 34: AC/N.
The 5 V auxiliary is 4.5–5.5 V at 0.3 A maximum; the 12 V auxiliary is 10.8–13.2 V at 0.8 A maximum. They are referenced to isolated GND-AUX pin 31, include OR-ing isolation and are not switched off by remote control.
AC OK is low at 0–0.5 V when input is ≥87 VAC, and high at 4.5–5.5 V at ≤75 VAC. DC OK is low above 80% ±5% output and high below that threshold. T-Alarm and fan-fail outputs are low when healthy and high on the corresponding fault. Status outputs source 10 mA maximum and are referenced to isolated GND-AUX pin 31.
Address, DA/DB and PV signals are non-isolated and reference -V signal pin 9. Communication and status signals use isolated GND-AUX. Do not use +V/-V signal pins as load-current terminals. The LED is green when normal and red on a fault.
Mechanical Installation and Matching Equipment
| Body dimensions, L × W × H |
295 × 127 × 41 mm; 1U module profile. |
| Catalogue packing reference per unit |
2000 g (2 kg); not the carton mass. |
| Mechanical drawing |
Physical catalogue page 18; provide clearances for the handle, connector and mounting features beyond the listed body dimensions. |
| Matching shelf |
RKP-1UI / RKP-1UT / RKP-1UI-CMU1 / RKP-1UT-CMU1; separately specified rack equipment. The -CMU1 rack options include the RKP-CMU1 control/monitor unit. |
The RKP-1UI and RKP-1UT shelves without an installed CMU1 accept three RCP-2000 modules; the catalogue describes up to 6000 W per such shelf and 18000 W across three such shelves, subject to voltage-model ratings and derating. RKP-1UI-CMU1 and RKP-1UT-CMU1 instead have two power-module slots plus the RKP-CMU1 control/monitor unit, as shown on catalogue page 42. The three-module and three-shelf headline powers do not apply automatically to these two-module configurations. A controller can monitor at most nine supplies; choose the power rating from the actual installed modules and configuration.
The module, rack shelf, control/monitor unit and mating connectors are separate configuration items unless expressly included in the ordered assembly. Use the exact connector reference and the model-specific pin assignment; a shared connector shell does not make different RCP families electrically interchangeable.
The mechanical drawing shows the fan/handle side opposite the electrical connector side; maintain the illustrated insertion, handle and ventilation clearance.

The catalogue lists a five-year warranty. Optional conformal coating is a separately specified configuration; it is not implied by the standard model code.
