MEAN WELL Rack Mount Power & Charging Systems
Global System Features
The MEAN WELL Rack Mount System provides highly scalable, centralized power distribution and battery charging architectures suitable for industrial automation, datacenters, telecommunications, and high-power EV/battery applications.
- Dual Application Architecture: Available in both standard Power Supply formats (RHP/RCP/RKP) and dedicated Battery Charging formats (RHB).
- Scalable Power: Start with a single 1000W/1600W module and scale up to massive multi-kilowatt rack arrays (up to 8000W per 1U shelf).
- Hot-Swappable Modules: Rectifiers and chargers can be inserted or removed without powering down the system, ensuring zero downtime.
- Intelligent Digital Communication: Supports advanced protocols including PMBus, CANBus, and I²C for real-time monitoring and control.
- Standard 19-Inch 1U Profile: Designed to seamlessly integrate into standard server and telecom racks.
Front-End Rectifier & Charger Modules
| Model Series | Max Power | Output Voltages | Communication Protocols | Key Features |
|---|---|---|---|---|
| RCP-1000 | 1000W | 12V, 24V, 48V | I²C (Optional) | Cost-effective, AC OK/DC OK signals, 5V/0.3A Aux. |
| RCP-1600 | 1600W | 12V, 24V, 48V | PMBus / CANBus (Optional) | Programmable Voltage (PV) & Current (PC), High density. |
| RCP-2000 | 2000W | 12V, 24V, 48V | PMBus | Ultra-high power, Output programmable, 5V/0.3A Aux. |
Universal Input: All RCP series feature a wide input range of 90~264VAC with active PFC. Note: Charging specific modules (like RCB series) pair with the RHB racks.
1U Rack System Shelves
These 19-inch 1U rack shelves provide the housing, parallel busbars, and communication backplanes for the modular systems.
| Rack Model | System Type | Max Module Slots | Max Shelf Power | Connections |
|---|---|---|---|---|
| RCP-1U | Power System | 3 Slots | 3000W | IEC320-C14 or Terminal Block |
| RHP-1U | Power System | 5 Slots | 8000W | IEC320-C14 or Terminal Block |
| RHB-1U | Charging System | 5 Slots | 8000W | IEC320-C14 or Terminal Block |
| RKP-1U | Power System | 3 Slots | 6000W | IEC320-C20 or Terminal Block |
Power Control and Monitor Units
Intelligent control modules allow users to monitor system health, adjust output parameters, and manage alarms remotely or locally.
| Model | Compatibility | Key Specifications & Features |
|---|---|---|
| RCP-MU | RCP-1000 / RCP-1U |
• 1U profile (can be rack-mounted or standalone). • Decodes I²C signals from RCP-1000. • Digital display for voltage, current, and internal temperature. • Remote ON/OFF control and ±10% voltage trimming. |
| RKP-CMU1 | RCP-1600 / RCP-2000 / RKP-1U / RHP-1U / RHB-1U |
• Fully digital control unit with 16x2 LCD display. • Supports PMBus communication. • Interfaces: USB, RS-232, and Ethernet for PC/Network integration. • 4 programmable relay contacts. • Manages voltage, current, temperature, and fault status across the entire rack. |
System Ordering Configuration
A complete operational system requires selecting the Front-End Module, the corresponding Rack Shelf (Power or Charging), and optionally, a Control Unit.
| Component | Power System Example | Charging System Example |
|---|---|---|
| 1. Module | RCP-1600-48 (1600W Power Module) | RCB-1600-48 (1600W Charger Module) |
| 2. Rack Shelf | RHP-1UI (Standard Power Rack) | RHB-1UI (Dedicated Charging Rack) |
| 3. Controller | RKP-CMU1 | RKP-CMU1 |
Assembly Note: Ensure your application matches the rack prefix: Use RHP for standard DC power supply setups, and RHB for battery charging configurations. Control units like RKP-CMU1 may have specific firmware compatibility requirements.
