AMF Panel
An AMF panel watches the utility supply. When the mains fails or goes out of limits, it starts the diesel generator, transfers the load to it once voltage and frequency are stable, and transfers back and stops the generator after the mains returns.
AMF panels are matched to the generator rating and controller, and pair naturally with the DG sets we supply.

Choosing an AMF panel
An AMF panel watches the mains supply. When it fails or goes outside limits, the panel starts the generator, waits for voltage and frequency to settle, and transfers the load; when mains returns and stays healthy, it transfers back and runs the set on cool-down before stopping. Changeover can be through contactors, motorised changeover switches or ACBs, depending on the rating.
Size the panel to the DG set rating and the incomer of your main panel, and decide on the controller features you need – engine protection, event logs, remote monitoring. AMF panels suit both open and silent diesel generators; to run several sets together, see the DG synchronising panel. Our guide on sizing a diesel generator helps fix the kVA.

AMF Panel – FAQ
Is an AMF panel needed with every generator?
It is needed wherever the generator should start and take over the load automatically. Without it, the changeover is done manually.
