Working Principle
The GKD120-400CVC Industrial Battery Charger Rectifier System converts three-phase AC input into regulated DC power through advanced high-frequency switching technology. As a 120V 400A Industrial DC Power Supply, it provides stable DC output for connected industrial loads while charging the battery bank through adjustable equalization and float charging modes.
During normal operation, this High-Frequency Switching DC Rectifier supplies continuous DC power to connected loads and maintains the battery bank in a charged condition. When AC input power is interrupted, the connected battery bank can automatically provide backup power to the DC loads, depending on the system configuration. Combining an Industrial Battery Charger and a 120V DC Rectifier in one system, the GKD120-400CVC offers an integrated solution for industrial DC power supply and battery backup applications.
