Grid connection with or without synchronisation

In the event of a significant loss of mains power or total blackout, Automatic Mains Failure (AMF) performs an automated power switch to emergency standby generators, preventing possible data loss and potential damage to electrical equipment.

AMF with synchronisation

With synchronisation preventing at least one blackout when switching from generator to mains grid supply, this is the most common AMF variant. Select immediate opening of breaker, or with load across before opening. You can also select overlap to make short-time parallel of generator to grid possible for, for instance, 0.1 second. Controllers: AGC 150 / AGC-4 MK II

AMF without synchronisation

This application is mainly used for simple systems intended only for AMF control. In both cases, switching from mains to generator supply and back is performed with a short-term blackout. Controllers: SGC 420 MK II / SGC 120 MK II / AGC 150
