ABB馬達(dá)啟動器MS116-16.0 現(xiàn)貨特價供應(yīng)
The load is transferred from a common power supply to a standby power supply,
Change the load back to the common power supply (and phase protection).
The switch may be set according to user requirements of power down when the switching voltage range.
The working voltage of the switch controller is AC220V. Switch mechanical life (N-R-N cycle) for 5000 times.
Minimum conversion b time is 1.5~4S. Switch with pressure, under voltage, overvoltage, phase failure, delay, start the engine, fire,
Since the b is not self recovery, standby priority, switching function. Use the switch to operate the handle as an emergency manual switch.
(in the case of power failure) with three stable working state: state I: common power supply, standby power supply,
State II: commonly used power points, standby power supply; state III: common power points, spare power points.
