Product Overview
The TH110D20NZ-3G is an industrial-grade intelligent high-frequency switching power supply module designed by Shijiazhuang Tonghe Electronics for global power systems and demanding industrial applications.
As a high-power natural cooling model in the -3G series, this module employs resonant voltage-type dual-loop control technology to deliver a rated output of 110VDC/20A (3KW) with exceptional stability and reliability. With efficiency ratings ≥93%, power factor ≥0.93, wide input range of 304~456VAC, and adjustable output of 88~150VDC, it provides high-purity stable DC power for high-power electrical equipment and industrial loads, meeting Class Ⅰ load continuous operation requirements.
Advanced Features
  • Supports N+1 hot backup and parallel operation with current sharing imbalance ≤±3%
  • Built-in RS485 interface compatible with Modbus/TonHe dual protocols
  • Comprehensive protection: overvoltage (160±8VDC), short-circuit, overtemperature, and overcurrent
  • LED digital display, keys, and DIP switches for flexible operation
  • Supports independent/manual/automatic operating modes
  • Hot-swappable design for efficient maintenance and minimal downtime
  • Natural cooling design with weight ≤16kg for easy installation
Operating Environment
Designed for stable operation in environments ranging from -10℃ to +40℃, with humidity ≤90% at 25℃, and altitudes up to 2000m. The module resists conductive dust and corrosive gases, making it suitable for substations, power plants, industrial power distribution systems, and new energy storage stations.

Protection Features
  • Load Rating: Continuous operation at 100% rated output current (Class I)
  • Automatic Current Limiting: When output current exceeds the set limit, the module operates in constant current mode and the output current will not increase
  • Output Overvoltage Protection: The module automatically stops output when voltage exceeds 160±3VDC to prevent equipment damage
  • Output Short-Circuit Protection: The module self-protects in case of short circuit to prevent damage and automatically recovers after fault removal
Note: Voltage regulation accuracy does not include the effect of the built-in isolation diode.
