Product description

High-frequency switch power supply charger adopts international advanced “voltage dual-loop resonance soft switch technology” and combines with DSP control, with excellent features such as high efficiency, small volume and light weight. Front end is equipped with source PFC module, with the features such as small volume, high efficiency, natural (air cooling) cooling, low operation noise, and little pollution to power grid. It is suitable for a certain capacity configuration DC system which is composed by   co-manufacturer through components, and applicable to electric operation power system (including power plant, hydropower station, various transformer substations, electric motorcycles and the sites needing DC power supply) and communication power supply system to meet functional requirements including charging for daily maintenance of storage battery, divide-shut brake of operating mechanism, control protection, accident lighting and communication.
