4. Case Sharing


The product is used for voltage stabilization for factories or electrical equipment. There are many successful cases in related to this 500KVA insutrial high power voltage stabilizer.


Here is an example. In 2017, a purchaser from Thailand bought a 500KVA voltage stabilizer. The voltage condition in his plant is very bad at that time. He found us and communicated with us about the details. The input voltage could be 320V to 420V, with 100V's fluctuation. The total load of his factory is about 250KVA. We suggested that he buy a three phase votlage stabilizer with 500KVA's rated capacity. Later, he bought the product and the voltage stabilizer performs very well now in his factory.
