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.
