WA20KM series charger module is a low-voltage and high-current charging power supply module with two industry-leading advantages: ultra-wide output voltage range and ultra-large charging current.
Product introduction
Main Features
1. Wide output voltage range, 200Vdc~1000Vdc.
2. Wide operating temperature range at full power, -40℃~75℃;
3. Full load efficiency is higher than 95%, high efficiency in the whole working range, and more energy saving;
4. high frequency transformer isolation;
5. low standby power consumption less than 10W;
6. The current in the low-voltage area does not shrink, and the charging speed is faster;
7. CAN bus communication;
8. The module is built with residual pressure relief loop to reduce system cost and improve system reliability.
