Detailed Product Description

This series large power automatic voltage stabilizer/regulator is an energy-saving new product

developed by our company by absorbing the advanced technology of Western Europe. It

is provided with two systems of manual/automatic dual control, direct output and

stabilizing output, with the functions of over/under-voltage protection, delay and error

protection etc, it is reliable and suitable for any load

Service Occasions :Widely used in the fields of post office, store, elevator, hospital,

school, publishing house and stock exchange where normal voltage is in need, and also

can be used in the factories of large and middle-scale industrial and mining corp. It is very

much suitable for some important devices and supporting single machine
