LB3D Series Double Power Automatic Transfer Switch

Specifications

1. Application 
TGDZ47 Series automatic transfer switching power supply is suitable for the double power supply system of AC50Hz, rated operational voltage 400V/230V, rated operational current up to 63A. Automatically trans-fer one or multi-load circuits from one power to the other power, to protect power supplied normally to load circuit. The device mainly used for industry, shopping center, bank, high building and so on. The device comply with IEC60947-6-1. 
2. Structure 
TGDZ47 automatic transfer switch is made up of MCB single motor mechanism control circuit, all parts are installed on a backplate. Control power voltage of automatic transferswitch is AC400V, mechanical life is 5000 times. 
3. Performance 
TGDZ47 automatic transfer switch(only R type that is automatically entry and automatically reset ) monitor phase voltage of double power supply(is named common power supply andstandby power supply) at the same time. When common power supply is malfunction, that is to say, A phase of MCB is voltage failure or phase failure, automatic transfer switch automaticallytransfer standby power supply with non-time delay; When common power supply returns tonormal, automatically transfer common power supply with non-time delay. Both power supplyare malfunction are not allowed.
