Publish time 2017-03-14 09:15
Introduction:This series large power voltage stabilizer 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.
