Product Overview
The TH230D20ZZ-3G is an industrial-grade intelligent high-frequency switching power supply module designed for global power systems and industrial applications. As a high-power natural cooling model in the -3G series, it employs resonant voltage-type dual-loop control to deliver a rated output of 230VDC/20A (6KW) with robust and stable performance.
With ≥93% efficiency, ≥0.93 power factor, 304~456VAC input range, and 176~300VDC adjustable output, this module features ±0.5% voltage regulation, ±1% current regulation, and ≤1% ripple coefficient. It provides high-purity stable DC power for high-power electrical equipment and industrial loads, meeting Class Ⅰ load continuous operation requirements.
Advanced Features
  • N+1 hot backup and parallel operation (current sharing imbalance ≤±3%)
  • Built-in RS485 interface compatible with Modbus/TonHe dual protocols
  • "Four-remote capabilities" for seamless automation system integration
  • Comprehensive protection: overvoltage (320±16VDC), short-circuit, overtemperature, overcurrent
  • Automatic fault recovery without affecting system operation
  • LED digital display, keys, and DIP switches for flexible operation
  • Supports independent/manual/automatic operating modes
  • Hot-swappable design for efficient maintenance
  • Natural cooling with proper ventilation requirements
Environmental Specifications
Operating temperature: -10℃~+40℃ | Humidity: ≤90% at 25℃ | Altitude: ≤2000m
Resistant to conductive dust and corrosive gases. Widely used in substations, power plants, industrial power distribution systems, and new energy storage stations.
