220VAC+_15% to 260-400VDC 2A high frequency battery charger
Main Function
Intelligent high-frequency switch power supply modules are developed based on the patent technology "resonant voltage dual loop control soft switching power transformation". They feature high efficiency and stability, small size and light weight.
- Output over-voltage protection
To prevent the disastrous accident caused by output overvoltage to electric consumers, there is overvoltage protection circuit in the module. When output overvoltage occurs, the module locks up automatically, the relative module fault indication light is on, the faulty module quits work automatically and doesn't affect the normal operation of the entire system.
- Output current limiting protect
The output current cannot increase infinitely. The maximum value of the output current of each module is limited to the rated output current 105%, in this range, the output current value of the module is continuously adjustable. If the load output of the module, the module will play down the output voltage
- Output short-circuit protection
When output short circuit, the module draws the output voltage to 0 immediately, limit the short circuit current below 15%limit current point to protect the module. The module will not be damaged under short circuit state for a long time, and can go back to work automatically after debugging.

| Automatic current limiting technology |
The output current cannot increase infinitely. When output current exceed limited current value, a constant current output. The maximum output current value of each module is limited to the rated output. |
| Output over-voltage protection function |
After output over-voltage occurs(440±20VDC), the module locks up automatically |
| Output under-voltage protection function |
When output voltage below 220±20VDC, module fault light alarm, fault outside node close |
| Output short circuit protection |
When the output current get short circuit, the module will protect itself from broken. After the faults get removed, it will restart working automatically. |
