What is an Automatic Transfer Switch (ATS)?
An automatic transfer switch transfers critical power loads to the most stable power source to ensure sustainable up time in mission-critical applications. Typical usage is in mission-critical applications where the power must stay on: hospitals, financial and data centers.
Features:
1) Provided with such protective functions as checking two sources of voltage at the same time, protection when any one phase or one phase above experiences under- or over-voltage, guide phase
2) When two sources haveATS (Automatic Transfer Switches )YES1-500S
Features:
1) Rated current of over current release: 40A,63A,80A,100A,125A,160A,200A,250A,315A,400A,500A
2) Pole number: 2p, 3p, 4p
3) Rated working voltage: AC 400V, 50Hz
4) The total height is only 110mm
5) Good function connection:UTILITY - UTILITY,UTILITY-GENERATOR
abnormal or faulty tripping (overload, short circuit), the controller won't send out the order to realize the protective function of reopening and closing
3) Four working modes: automatic control, common source (power supply I), standby power supply (power supply II), breaking electricity (re-tripping)
4) When the working mode is in the automatic control state, it has two self-throw no self-recover, self-throw, and self-recover functions:
a) Self-throw non-self recover: when the device enters the working state, power supply I automatically throws into supplying electricity; when power supply I has an abnormity, it will automatically transfer to power supply II; when power supply I recovers, it doesn't transfer until power supply II has an abnormity, then it will automatically transfer to power supply
b) Self-throw and self-recover: when the device enters the working state, the common source throws into supplying electricity; when power supply has an abnormity, it will automatically transfer to standby power supply; when common power supply recovers, it will automatically recover common power supply; but when the standby power supply has an abnormity, the controller will emit an alarm sound.
