ATS and AMF panels both keep the lights on when the utility fails, but they do different amounts of work.
ATS — Automatic Transfer Switch
An ATS transfers the load between two live sources — typically utility and generator — when the primary fails, and transfers back when it returns. It switches; it does not start the generator.
AMF — Auto Mains Failure
An AMF panel does everything an ATS does and also starts and stops the generator automatically. On mains failure it signals the genset to start, waits for stable output, transfers the load, then reverses the sequence when mains returns.
Which to choose
- Manned site or generator with its own auto-start → an ATS may be enough.
- Unmanned or critical site that needs the generator to start on its own → AMF.
- Multiple generators that must share load → add a synchronizing panel.
NIXCO builds ATS, AMF and synchronizing panels around your generator controller and load.
