Automatic Transfer Switch Cabinet (АTS) is designed to manage and switch between primary and backup power supplies and back again.

The АTS ensures network protection in case of deviations of the current load from nominal values, monitors phase sequence, and prevents phase sticking.

The cabinet also allows configuration of automatic and manual operation modes, adjustment of switching time to the backup source and back to the main supply, as well as operation mode indication.

The cabinet includes components such as the PEF-321 АTS module, RNPP-311М control relay, REV-201М time relay, circuit breakers, RCDs with a differential current of 300mA, contactors, and other equipment.

At the customer’s request, the ШК АВР can be equipped with components from leading global manufacturers in the electrical engineering field, such as IEK, EATON, or Schneider Electric.

The cost of the cabinet depends on the chosen manufacturer of the components.

The control cabinet allows the organization of:

• Management and switching between two urban (stationary) power inputs (networks) in case of parameter deviations beyond set limits
• Activation of a generator and switching the load to it in case of deviations in the stationary network parameters
• Protection of the load and generator from network failures, specifically:
• a) Voltage deviations from nominal values
• b) Phase sequence issues
• c) Phase imbalance
• Switching time to the backup source
• Operation in automatic and manual modes
• Indication of operating modes
