We provide isolation Transformer as a seperate part, wherever necessary to the senstive loads from abnormal input , which is highly increased the life of the load / equipments.

For three-phase output application, we import the basic module. Along with that we supplies other items like Bypass line equipment & Distribution board manufactured by us, Batteries procured from domestic battery vendors & integrate the system at site.

Ranges :10,15,20,30,40,60,80,120,160,200,250 & 300 KVA
