Product Introduction
The TH600X02ZZ-220AC Fire Protection Power Supply Module utilizes resonant voltage dual-loop control technology to deliver stable DC output from 450V to 600V (nominal 524V). Designed for single-phase 220VAC input, it features a standard RS-485 interface for easy integration into automated monitoring and control systems.
Product Advantages
High efficiency up to 93% with natural cooling and compact size
Modular N+1 hot redundancy design supports scalable system expansion
Comprehensive protection includes overvoltage (640±20V), output current limiting, short-circuit, and overcurrent safeguards
Built-in isolation diode and autonomous current sharing (deviation ≤±5%) simplify parallel operation
User-friendly LED display and DIP switches for easy configuration and manual adjustment
Application Scenarios
Ideal for fire alarm systems, emergency lighting, and other critical safety equipment in commercial buildings, industrial facilities, and infrastructure projects requiring stable, remotely manageable DC power with high reliability and system flexibility.

Protection Features
Automatic Current Limiting: Once the output current reaches the set current limit, the module automatically switches to constant current operation, preventing any further increase in output current.
Overvoltage Protection: If the output voltage exceeds 540 ±20 VDC, the module automatically stops output to prevent damage to connected equipment.
Short-Circuit Protection: During an output short-circuit, the module self-protects to prevent damage. After the fault is cleared, normal operation is automatically restored.
Note: Voltage Regulation Accuracy excludes the effect of the built-in isolation diode
