400V Dual Power Automatic Transfer Switch 4P Intelligent Controller

Automatic Transfer Switch -(PC level) FMIQ8

Structural features and functions

- FMIQ8 type as the main and backup dual power supply automatic transfer switch adopts electromagnetic drive, electrical and mechanical simultaneous chain mechanism, the main circuit contacts are static and dynamic structure, the dynamic contact tip adopts V-type design, in order to avoid long-term electromagnetic coil charged, using electric closing, mechanical maintenance, so the operating mechanism in the steady state working conditions, without providing working current, energy-saving significant. The control power supply is drawn from the main backup power supply AC 220V (no need to add another control current), due to the superior structural characteristics, so the backup power supply will not be connected at the same time, to ensure that the common and backup power supply work reliably without interfering with each other, the switch has electrical or mechanical closing instructions, and at the same time can provide customers with normally open and normally closed passive contacts for other uses.

-Intelligent controller also provides with loss of voltage, undervoltage, overvoltage, conversion delay control, generator signal control, feedback signal and other functions, and strong anti-interference ability.

-With self-injection self-repeat; self-injection not self-repeat; mutual standby three conversion modes.

-Two-segment type has common power supply together, standby power sub; common power sub, standby power together; two stable working positions

-Three-stage type has common power supply together, standby power supply separately; common power supply separately, standby power supply separately; common power supply separately, standby power supply together; three stable working positions.

-Easy and convenient installation.

-A special handle is available for manual conversion in the manual state.
