321АВР manages the automatic transfer from the primary three-phase power source to the backup source and back, in cases of unacceptable voltage deviations in the phases, asymmetry or phase imbalance, phase sequence changes, or the loss of one or more phases in either the "primary" or "backup" networks.
The device can be used in power supply systems as part of:
321АВР monitors voltage at two inputs of three-phase, four-wire networks (230/400V) with either a grounded or isolated neutral configuration.
