Electricity is needed on all electronic equipment. Ranging from household utilities, public facilities until to the industrial environment. But in everyday life, there are times when the power goes out either because of natural factors or because any maintenance or other causes unexpected. That why we producing UPS (Uninterruptible Power Supply). When the power is on, the UPS will save power on battery (the amount of battery power depends on the type of output selected / used; greater output power on, the amount of battery will be more and more).

And when the power goes out, the UPS system will change the DC (Direct Current) voltage to AC (Alternating Current). Our UPS design is using the latest microprocessor system as the controller. That why our product is high reliability due to best design and low component count.

We have 3 type UPS:
