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
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.
