Core Functional Features
- High Voltage DC Wide Input Adaptability
Stable operation within 88–140 V DC wide high-voltage DC input range, perfectly matches industrial high-voltage DC power distribution systems on site.
- Redundant Hot-Standby Power Architecture
Supports dual-module primary/backup redundant installation; backup module automatically switches to supply power when primary module fails. Power supply switching does not interrupt system operation.
- Complete Multi-Level Protection Circuits
Built-in reverse polarity, overvoltage, overcurrent, surge and short-circuit protection, effectively prevents damage to system modules caused by abnormal power grid fluctuations.
- Plug-in Hot-Swap Design
Supports online plug and replacement without powering down the entire monitoring system, greatly reduces maintenance downtime and operation interruption.
- Real-Time Power Status Monitoring & Diagnosis
Equipped with HV OK and Fault indicator lights; automatically uploads power abnormal status to system host and upper computer platform in real time.
- High-Stability Isolated Power Conversion
Adopts high-efficiency isolated switching power supply topology, low ripple output, strong anti-interference performance, ensures stable power supply for precision monitoring modules under harsh conditions.
- Standard Half-Height Rack Structure
Compact half-height module design, saves rack space, fully compatible with all standard 3500 system racks.
