MEAN WELL RCP-1UI is a 19-inch, 1U rack shelf with IEC 320-C14 AC inlets for up to three RCP-1000 front-end power modules. This ordering code identifies the shelf, not a fully populated power supply. Output voltage, power, cooling and communication depend on the separately selected modules and complete system configuration.

Configuration and Matching Modules
| Ordering form |
RCP-1UI; bare rack shelf. |
| Module capacity |
Up to three matching RCP-1000 modules, connected for active current sharing. |
| Compatible voltage families |
RCP-1000-12 / RCP-1000-24 / RCP-1000-48; corresponding C-suffix versions provide I²C. Select a consistent output-voltage configuration. |
| Assembled system ordering |
RCP-3K1UI-12, RCP-3K1UI-24 or RCP-3K1UI-48; add -C for the catalogue I²C-equipped whole-system option. |
A fully populated three-module system is rated at 2160 W for 12 V, 2880 W for 24 V, or 3024 W for 48 V before applicable derating. These are system ratings, not output ratings of an empty shelf. Rack, modules and mating connections must be specified as the intended assembly.
Rack Construction and Installation
| Rack width × depth × height |
483.6 × 350.8 × 44 mm; 19-inch, 1U format. |
| AC connection |
Three IEC 320-C14 AC inlets, one per module position. |
| Power output |
Use the rack bus/output terminals marked +V and -V; CN500 signal pins are not load-current terminals. |
| Side mounting |
M5 screws; maximum penetration depth 6 mm, recommended tightening torque 10 kgf·cm. |
| Mechanical clearances |
Physical catalogue page 23 shows the handle projection, rear terminals, rack ears and air path; keep the module fan inlets and rear exhaust clear. |
| Control connector |
CN500: female, right-angle 25-position D-type connector. Select its mating part to the actual connector drawing and wiring requirements. |
The shelf is designed for RCP-1000 modules; the differently wired RHP-1U and RKP-1U families use their own module and system documentation.
Rack Control Interface
CN500 groups A/B/C: remote ON/OFF pins 1/8/15, AC OK pins 2/9/16, DC OK pins 3/10/17, V TRIM pins 4/11/18, and T-Alarm pins 5/12/19. Short each remote input to -S pin 21 for ON; leave it open for OFF.
CN500 pin 6 is 5V-AUX, 4.3–5.3 V at 0.3 A maximum; pin 7 is its isolated return GND-AUX. This OR-ing-isolated auxiliary remains available when remote control disables the main output. Pin 14 is CS; link CS between parallel units for current balance.
Pins 20/21 are +S/-S. Connect a twisted sense pair to the load for up to 0.5 V drop compensation. For local sensing link pin 20 to +V signal pin 22 and pin 21 to -V signal pin 25. Pins 23/24 are SCL/SDA for the I²C-equipped system configuration.
AC OK is low at 0–0.5 V when input is at least 82 V ±4 V and high at 4.5–5.5 V below that threshold. DC OK is low when output is at least 80% ±5% of nominal and high below that threshold. T-Alarm provides a module temperature-warning output; confirm its applicable CN500 logic level in the supplied rack interface documentation before connecting a shutdown or interlock input.
The installed module voltage determines the external-resistor values for 90–110% voltage programming. Use the corresponding 12, 24 or 48 V table on physical pages 21–22; the shelf alone does not define an output voltage.
System Integration Conditions
The RCP-1000 module input specification is 90–264 VAC or 127–370 VDC, 47–63 Hz. Apply the installed modules’ current, protection, temperature and input-voltage derating requirements; the maximum ambient rating does not authorize full load at every input or temperature.
The catalogue RCP-1U system supports hot-swap modules and active current sharing. It describes up to approximately 3000 W per shelf and 8000 W across three shelves, subject to the chosen voltage models and system limits. All installed RCP-1000 outputs operate in parallel.
The RCP-1U catalogue lists a five-year warranty. Electrical safety and EMC specifications apply to the specified complete power-supply system; verify the completed equipment and its wiring for the intended installation.
