Trade Lead Description:
AMF relays is solid state, compact electronic device for automation of DG set.
On Mains failure, or any of the mains phase dipping below set voltage, it signals to starts the DG set.
On picking up the momentum, it withdraws the cranking signals. Load is connected to the DG only after minimum set voltage has been built up.
On resumption of mains supply with minimum level of all the phases, it signals a mains delay timers. After the preset time and availability of healthy supply, it signals the transfers of load to mains and simultaneously signals to stop the DG set.
It incorporate various timers, voltage sensors, counters, logic control etc. It does not require any separate battery back up. The battery connected for operating the DG set is used as Aux. supply source.
