AMF panels (Automatic Mains Failure panels) are sometimes referred to as ATS panels. Like ATS systems, AMF panels monitor the incoming power supply from the mains and automate the switch to the standby generator source in the event of an outage.Having an AMF panel in place means users won’t have to manually manage the switch to standby generator in an emergency, which can lead to data loss or major disruption.

So, both AMF and ATS panels switch the electrical load from the regular mains supply to the backup generator. So what’s the difference between the two? The main difference between the two types of generator panels is the way they’re started. ATS panels use a volt-free contact system with the mounted set control panel to start and stop the generator. However, AMF panels have a dedicated generator controller with alarms for stop, start, water temperature, fuel oil pressure and full level. However, in many cases and in many systems, the terms ATS and AMF are used interchangeably. For that reason, it’s always worth having a member of the Vital Power team provide recommendations and regular check-ups for your critical power set up. If your generator system has a Generator Control Panel (GCP), we’d typically recommend using an ATS panel for switching to generator power. If your generator doesn’t have its own Generator Control Panel, an AMF is required to maintain proper usage.
