YES1 series Intelligent Dual Power Automatic Transfer Switch PC-class YES1-Q

Structure and Characteristics of Intelligent Dual Power Automatic Transfer Switch PC-class:
YES1 series intelligent dual power automatic transfer switch consists of switch entity and transfer controller. This dual power automatic transfer switch applies electromagnetic drive while the transfer controller adopts a 220 V 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.
YES1-Q Intelligent Dual Power Automatic Transfer Switch
Rated current:630A~3200A

Functions of Dual Power Automatic Transfer Switch PC-class(YES1-Q):
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.
Integrated ATS type with interior controller.
Split ATS type with outer controller.
One pair of passive contact can transmit to start generator function.
Types and Functions of Controllers Used in Automatic Transfer Switch:
Brief Introduction of YCU-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 to another power supply to output to the load;
-Any path appear over-voltage, under-voltage, lack 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 30S;
-Two modes of operation: manual and automatic, hand regulation.
