RH-ATSQ1 Dual Power Automatic Transfer Switch (A.T.S for short)
applies to the terminal double-loop power supply system that
50Hz/60Hz, rated operating voltage 220V(2p),380V (3p and 4p), rated
current 10 ~ 63 A. It can automatically switch the normal power to
reserved power to prove the reliability of power supply, mainly
used for fire pumps, smoke fans, elevators, pumps, lighting in
high-rise buildings, shopping malls and other places.
When the main power supply is normal,using the automatic model,the
circuit breaker of reserve power supply is off,the circuit breaker
of main power supply is on.When one phase or all three phase of the
main power supply is off,the ATS will convert to the reserve power
supply(the reserve power is normal),when the main power is
normal,the reserve power will recover back to main power again.
