YES1 series Intelligent Dual Power Automatic Transfer Switch PC-class YES1-125N

Structure and Characteristics of YES1 series 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.
YES1-125N Intelligent Dual Power Automatic Transfer Switch (fission of two-segment)
Rated current: 40A ~ 125A
Poles: 2 P, 3P, 4P
Functions of Automatic Transfer Switch PC-class (YES1-125N):
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 YES1-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 YES1-C;
One pair of passive contact can transmit to start generator
Types and Functions of Controllers that Used in Automatic Transfer Switch:
Functions of YCU-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 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.
