Detailed Product Description

It can detect two power sources`s three phase voltage in three phase four wires utility system.It have short circuit ,over load protection. And any phase occur over voltage,under voltage,lost phase
those faults,it will changeover to the other normal power source.

 Function.Controller B:
1. It can exact display two ways power
source three phase voltage,frequency
and switch status;
2. User can set the parameter about
working status,transfer delay time and
so on.
3. It can set self-input and
self-recover,self-input without
self-recover,Utility to generator
model.
4. Fire protection warning
interlock,transfer to double break
position
5. In Utility model can send generator
start signal
6. transfer delay time variable set
7. It with strong anti- disturbance,it can
value:145~210V variable
