ZGS1-M Automatic Transfer Switches (ATS)

Structure and Characteristics of ZGS1 series IntelligentDual Power Automatic Transfer Switch PC-class:
ZGS1 series intelligent dual power automatic transfer switch consists of switchentity and transfer controller. This dual power automatic transfer switchapplies electromagnetic drive while the transfer controller adopts a 220 V ACwith a main and a standby power supply, no additional power to control. Switchentity itself can also use the electric or mechanic off signal as the isolationindicator.
ZGS1-M Intelligent Dual Power AutomaticTransfer Switch:
Rated current：630A~1600A
Poles：3P,4P
Functions of transfer switch PC-classZGS1-M:
Simultaneously detect two lines power supply of three-phase four-wire grid.
It has several protection functions such as over-voltage, under-voltage and lack of phase and so on.

Split type of ATS with the controller.
One pair of passive contact can transmit to start generator function.
Types and Functions of Controllers Used inAutomatic Transfer Switch:
Brief functional introduction of ZCU-A -type controller’s functions:
-Indicate the current state of put- in circuit;
-Indicate the current on/off state of switch;
-Any path stops the power supply, its control switch automatically transform toanother power supply to output to the load;
-Any path appear over-voltage, under-voltage, lack phase, its control switchautomatically transform to another power supply to output;
-Two-path power supply at the same time, its control switch transform to themain power output (self-transfer and self-recovery) , users can ask forself-transfer and self-recovery or stand-by precedence circuit;
-It is available to supply compulsive and adjustable delay within the range of30S;
-Two modes of operation: manual and automatic, hand regulation.
