Sine wave inverters

1,Super wide input voltage :90V~300V
2,Output pure sine wave
3,Completely controlled by CPU to enhance the stability and reduce the cost
4,Open the inverter automatically when connecting the commercial power
5,Super wide input voltage : 90V---300V，and it has a switch , the switch can change the commercial power input range.
 when it was 90V---300V, it is used for INVERTER, but when it was175V---265V, it is used for UPS .
6,Be able to drive strong loads, such as tube lights ,refrigerator, air-conditioner and so on. 500W inverter can drive 4 tube lights, 4 fans.
7,Protection against short-circuit.
8,Transfer automatically, and transfer time is no more than 4ms. When the commercial power is cut off accidentally, it will protect your computer and server, and you no need to reset them.
9,Protection against overload. It will prompt you and shut down gradually.
