Automatic transfer switch HKSZ12

△ Ensure uninterrupted operation of critical power.

When one power supply has over-voltage, under-voltage or phase failure, it automatically switches to another power supply or starts the generator. It is suitable for hospitals, shopping malls, banks, hotels, high-rise buildings and firefighting, which are important places where long-term power outages and uninterrupted power supply are not allowed.

△ Complete automatic power supply conversion system.

Equipped with three conversion modes of automatic transfer and automatic recovery, automatic transfer without automatic recovery, and mutual backup, and two operating modes of power grid-power grid and power grid-generator are available to meet different power conversion needs.

△ Intelligent.

With communication interface, built-in RS485, MODBUS-RTU and meter 1997 protocol two communication protocols, data upload, remote data configuration and status monitoring can be realized, remote signaling, telemetry, remote control, remote adjustment functions can be realized, remote viewing function can also be realized with intelligent power distribution system,

△ Safe and reliable, with fire linkage function.

When a fire occurs in a non-fire load, the fire control center sends a signal to the intelligent controller to cut off the dual power supply and ensure that the fire load is powered off.

Complies with standards: GB/T14048.11, IEC60947-6-1
