Detailed Product Description

DBW/SBW Series full automatic compensated voltage stabilizers
General
DBW/SBW Series full automatic compensated voltage stabilizers is an energy-saving new product developed by our company absorbing the advanced technology of international same product,with the functions of over/under-voltage protection,delay and error protection.It has advantages of small volume,light weight,large capacity,high efficiency,wide range,high precision,strong protection,without wave-form distortion,reliable operation and easy installation,etc.
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.
