Specifications

DBW/SBW automatic voltage stabilizer
1:rate capacity :10-2000KVA
2:Input: 380+/-30%
3:output: phase voltage: 220V/380v

voltage stabilizer Application :

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.

 

Technical Index
