MEAN WELL High-Power Intelligent Chargers & Rack Systems (1600W ~ 12800W)
Global System Features
This high-power ecosystem is designed for heavy-duty industrial charging, telecom, datacenter backup, and EV infrastructure. It offers both standalone enclosed units and scalable rack-mounted modules.
- Smart Communication: Integrated PMBus and CANBus protocols allow for advanced remote control, monitoring, and data logging.
- Programmability: Features Programmable Voltage (PV), Programmable Current (PC), and adjustable charging curves (via SBP-001 or communication bus) to support Lead-Acid and Li-ion batteries.
- High Power Density: Achieve up to 12.8kW in a single 1U 19-inch rack shelf.
- 2-in-1 Flexibility: The NCP series integrates both power supply and battery charging modes into a single unit, switchable via firmware/hardware.
- Active PFC & High Efficiency: Universal AC input with built-in active PFC, delivering up to 94.5% efficiency to minimize energy loss and thermal output.
- Hot-Swappable Design: Rack modules (RCB, DBR, NCP) support hot-swapping for uninterrupted system maintenance.
1600W Series: RPB & RCB
The 1600W tier is split into two form factors: the RPB (Standalone Enclosed Charger) and the RCB (Rack-Mountable Charger Module).
| Model | Form Factor | Output Voltages | Max Charging Current | Key Features |
|---|---|---|---|---|
| RPB-1600 | Standalone Enclosed | 12V, 24V, 48V | 100A (12V) / 55A (24V) / 27.5A (48V) | Built-in default 3-stage charging curves. PMBus/CANBus. Built-in ORing FET. Programmable PV/PC. |
| RCB-1600 | Rack Module (Fits RHP-1U) | 12V, 24V, 48V | 100A (12V) / 55A (24V) / 27.5A (48V) | Designed to slot into the RHP-1U rack shelf. Hot-swappable. PMBus/CANBus control. High power density. |
3200W Series: DBU, DBR & NCP
The 3200W tier offers massive power output per unit. It includes standalone chargers, rack chargers, and the highly versatile 2-in-1 NCP module (which includes a High Voltage DC option).
| Model | Type | Output Voltages | Features / Protocols |
|---|---|---|---|
| DBU-3200 | Standalone Charger | 24V, 48V | 110A (24V) / 55A (48V). Default 3-stage curve. PMBus/CANBus. Active current sharing. |
| DBR-3200 | Rack Charger Module | 24V, 48V | Front-end rack charger. Fits DHP-1U rack. Hot-swappable. Fully programmable. |
| NCP-3200 | 2-in-1 Rack Module | 24V, 48V, 380V (HV) | Functions as both a Power Supply AND a Battery Charger. Features an ultra-high 380VDC output option for centralized telecom/datacenter power. |
Note: The NCP-3200 is a revolutionary hybrid model. You can toggle between constant voltage power supply mode and intelligent battery charging mode via communication protocols.
Rack Integration: DHP & DHB Series
To deploy the 3200W rack modules (DBR and NCP), they must be housed in specific 19-inch 1U rack shelves, which provide the AC input connections, DC output busbars, and communication backplanes.
| Rack Shelf Model | Compatible Modules | Max Capacity | Total Shelf Power |
|---|---|---|---|
| DHP-1UT-A / B | NCP-3200 (Power/Charger), DRP-3200 (Power) | Up to 4 modules | 12,800W (12.8kW) |
| DHB-12K1UT | DBR-3200 (Charger) | Up to 4 modules | 12,800W (12.8kW) |
| DHP-1UT-BHV | NCP-3200-380 (High Voltage) | Up to 4 modules | 12,800W @ 380VDC |
Ordering Logic:
1. For enclosed standalone charging: Choose RPB-1600 or DBU-3200.
2. For scalable rack charging: Pair RCB-1600 with RHP-1U, or pair DBR-3200 with DHB-1U.
3. For 2-in-1 high-power datacenters/telecom: Pair NCP-3200 with the DHP-1UT-B (or BHV for 380V) rack.
