Features and function：
1. Pure sine wave output
2. CPU control technology, SCM control, brand MOSFET
3. Strong ability of impact resistance
4. UPS function and AC charger function
5. Wide input voltage range: 145-275V（AC220V); Four step AVR (three step -up, one step -down)
6. Protection: overload, short-circuit, overvoltage, under-voltage and over-temperature, etc.
Special overload protection: when it is overload, it will lock the unit automatically，when it restores，it will restart the unit automatically again.
