Low Voltage Panels
AUTO MAINS FAILURE (AMF)
Applications
- AMF Control Panel is for controlling two DG Sets, Master DG and slave DG.
- Auto mains failures (AMF) Panels is meant for controlling DG START / STOP sequence in accordance to the availability of utility power supply.
Features
We design & manufacture the AMF panels for various capacity & different make of Diesel EA set. This is a Module with Generator monitoring, protection and start facilities. Operation of the module is via three push-buttons mounted on the front panel with STOP, MANUAL and AUTO positions. Selection of the ‘Auto’ mode is confirmed by LED indicator, and monitors the incoming mains supply (3 Phase or Single phase). Should the incoming AC mains supply fall below a configurable pre-set limit, the generator will be started, and load transferred to the gen-set. When the AC mains supply returns to within limits, the module will transfer load back to the mains. The engine will be instructed to stop after a cool-down period. The module’s microprocessor provides a comprehensive functions.
