Structure and Characteristics of Intelligent Dual Power Automatic Transfer Switch ZGS1-32N:
ZGS1 series intelligent dual power automatic transfer switch consists of switch entity and transfer controller. This dual power transfer switch applies electromagnetic drive while the transfer controller adopts a 220V AC with a main and a standby power supply, no additional power to control. Switch entity itself can also use the electric or mechanic off signal as the isolation indicator.

ZGS1-32N Intelligent Dual Power Automatic Transfer Switch (fission of two-segment)
Rated current: 16 A ~ 32A
Poles: 2 P, 3P, 4P

Functions of Dual Power Automatic Transfer Switch PC-class (ZGS1-32N):
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 phase protection.
Split type of ATS, the line between the controller and the switch installed by the user and the wiring type is ZGS1-N.
Use a special-purpose connecting socket between split ATS and the switch entity then users only needs major loop connection and inserts the socket power supply and the type is ZGS1-C. One pair of passive contact can transmit to start generator.

Types of Controllers Classified by Functions Used in Automatic Transfer Switch:
Functions ZCU-A-type Controller:
Indicate the current state of put- in circuit;
Indicate the working state of switch;
Any path stops the power supply, its control switch automatically transform to another power supply to output to the load;
Any path appears overload, under-voltage, lack of phase, its control switch automatically transform to another power supply to output;
Two-path power supply at the same time, its control switch transform to the main power output (self-transfer and self-recovery), users can ask for self-transfer and self-recovery or stand-by precedence circuit;
It is available to supply compulsive and adjustable delay within the range of 30 S;
Two modes of operation: manual and automatic, hand regulation.
