1U Rack-Mount Integrated DC Power System with Dual Rectifier Slots Monitoring Unit RS485/LAN Interface

Product Overview

This 1U high rack-mount integrated DC power system is designed for applications requiring compact, high-efficiency, and remotely monitored power delivery. It integrates power input terminals, dual rectifier slots, output ports, battery connection, monitoring interface, and signal IO in one chassis.

The unit is ideal for telecom base stations, small-scale data centers, and distributed energy cabinets. It ensures stable -48VDC output while supporting remote communication and flexible IO expansion.

Product Key Features

1U Compact Design

Fits standard 19-inch racks, only 1U high, perfect for space-constrained installations.

Dual Hot-Swap Rectifier Slots

Accommodates two rectifier modules (one installed in photo), supporting redundancy or load expansion.

Integrated Monitoring Panel

Front-mounted LED display with buttons for system status, voltage/current display, and local configuration.

Multi-Protocol Communication

Equipped with LAN (Ethernet) and RS485 ports, supporting SNMP or Modbus for integration with NMS/BMS.

Multiple Output Connections

Front-side high-current DC output terminals (e.g., OUT1+, OUT1–) with plug-type connectors for reliable load connection.

Comprehensive IO Terminal Block

Rear-side terminal block with DI/DO, temperature sensor, battery voltage, and SPD (surge protection device) monitoring points.

Grounding and Safety Labels

Clear high-voltage and grounding symbols for safety compliance and ease of field maintenance.
