Automatic transfer switch devices (ATS):

Automatic transfer devices of the ATS type provide backup power to consumers during an unauthorized or planned shutdown of a permanent source of power supply. Designed to start the equipment, acting as a backup, which, in the absence of electricity, ensures the continuity of the technological process. Functional for restoring the operability of electrical installations under voltage up to 660 V AC with a frequency of 50 Hz.

The АВР series units are supplied with one-way service, they are applicable to power supply facilities with category 1 or 2. Electricity to the modules comes from two independent power sources, with mutual redundancy provided.

A power interruption from one source is allowed for a period of time that is necessary for automatic switching to a backup supply of electricity. In the future, in automatic mode, the circuit is restored to an emergency power supply schedule.
