1U Rack-Mount Integrated DC Power System with Dual Rectifier Slots, Monitoring Unit RS485/LAN Interface and Terminal IO
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.
Product Advantages
Highly Integrated
Combines power conversion, control, monitoring, and protection into a single unit.
Remote and Local Monitoring
Can be accessed locally via LCD or remotely via RS485/LAN interface.
Easy Maintenance and Expansion
Plug-in rectifiers and front-facing connections allow fast installation and troubleshooting.
Flexible Deployment
Suitable for tower-mounted cabinets, outdoor 5G enclosures, or micro data center UPS systems.
Cost-Effective and Modular
Scalable with only one rectifier at first, then expanded to two when needed.
