ATS(automatic transfer switch)

Operating Principle: When the main power source side relay detects the voltage signal (e. G. Under voltage, voltage loss), the standby side relay begins to run, and connects the time relay which is controlled by it. After time delay, intermediate relay is connected, offer power for rectifier Bridge which is controlled by it, drive the solenoid coil^when the main power recovers, the voltage relay begin to run. After time delay, the intermediate relay is connected, and offer power for rectifier Bridge, drive the solenoid coil, the main power source supplies power again while standby power stop power supply .
