Extreme Wide Range Voltage Stabilizer

Extreme Wide Range Voltage Stabilizer
Product Description

In the developing countries, especially the remote areas, the mains power is extremely unstable. And the input voltage range (especially the minimum voltage) is very wide. For example, the

low input voltage can be down to 88V (the rated line to neutral voltage is 220V) that results in

the electrical equipment cannot start and operate. The common voltage stabilizer cannot handle the extreme low and unbalance voltage. Even if those can reluctantly work, the output power is de-rated a lot due to low voltage and high current situation. A special voltage stabilizer with a step-up transformer can some how solve the problem, but it has the disadvantages of high

cost, low efficiency and more space occupation.
