Core Functions
24V to 48V DC Voltage Stabilization and Boost
Stabilize and boost the commonly used DC24V control power supply in power plants/industrial cabinets to 48V DC, providing standard 48V working power for remote communication equipment, industrial DCS, excitation matching communication units, and remote I/O devices.
Multi-module Parallel Redundant Power Supply
Support N+1 redundant parallel, automatic current sharing between modules. In the event of a single module failure, the load can be seamlessly switched to the remaining normal modules to ensure the continuous power supply of critical control systems.
Complete Hardware Protection Mechanism
Built-in overvoltage, undervoltage, overcurrent, short circuit, overtemperature, reverse connection protection; Locks the alarm when a fault occurs, and the panel indicator lights (POWER ON, ALARM, MESSAGE) provide intuitive indication of the fault type.
Data Power Failure Storage
Built-in lithium battery, the system can maintain internal parameters and fault records for a short time after power failure, facilitating post-fault analysis and traceability.
Remote Monitoring and Parameter Configuration
Through local RS232 debugging, you can set the output voltage, current-limiting threshold, alarm threshold, and current-sharing parameters, and upload real-time operation data to the upper-level monitoring system.

Typical Application Scenarios
Communication power cabinet for the UNITROL series excitation system of power generation units, providing power for remote signal acquisition, optical fiber communication devices
48V DC redundant power supply system for power, petrochemical, metallurgical DCS/PLC control systems
DC power supply for industrial remote I/O stations, communication base stations, RTU measurement and control equipment
