System Overview
The charging module adopts an intelligent high frequency switching power supply independently developed for power systems. This series of power supply features "four remote" functionality and utilizes world-leading resonant voltage type double loop controlled resonant switching power supply technology. It offers significant advantages including compact volume, lightweight design, high efficiency (over 95%), and exceptional reliability.
Available in 220V, 110V, and 48V series with dozens of varieties, the system is equipped with standard RS-485 interfaces for easy connection with automation systems. It is suitable for substations and switching stations (500kV to 10kV), power plants (15mw-60mw units), and key industrial projects like subways, oil fields, chemical industries, and metallurgy. The charging process aligns with the curve requirements for lead-acid and nickel-cadmium batteries, featuring intelligent management and temperature compensation.
