Product Description

AC220V+-15% Input to DC 190-300V Battery Charger High Frequency Switching Power Supply

Product Description

"BZA" series intelligent high-frequency switch power supply modules are specially developed to meet the demands of modern DC system. The charger rectifiers are designed with world leading patent technology "resonant voltage type soft switching power supply technology". They feature high efficiency and stability, intelligent control, small size and light weight.
 

1. High efficiency, up to 95%-96%;

1. Light weight, Small size
2. After the full bridge rectifying circuit rectifies 3-phase AC to DC, then adjusted by reactive PFC,  power factor>0.94;
3. Unequal current ratio of parallel connection<+/-3%, can ensure twenty modules work well by parallel connection.
4. Function against reverse connection
5. LED digital screen
6. Output overvoltage protection

To prevent the disastrous accident caused by output overvoltage, there is overvoltage protection circuit in the module. Once the output voltage is higher than the threshold,  the module locks up automatically and fault indication light is on, the faulty module quits work automatically and doesn't affect the normal operation of the entire system. The overvoltage protection threshold is set in the factory, 320V±5% for 220V series,  160V±5% for 110V series.

1. Output current limiting protect

The output current cannot increase infinitely. The maximum output current of is limited to 105% of the rated output current.

1. Output short-circuit protection

When short circuit, the output voltage drops to 0 immediately. Limit the short circuit current under 15% of rated output current. The module will not be damaged under short circuit state for a time, and resumes to work automatically after debugging.
