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
