APFC Panel
Automatic power factor correction panels that switch capacitor banks in steps to hold your power factor near the target and help avoid utility penalties.

AMF Panel
Auto mains failure panels that start your diesel generator when the grid fails, transfer the load, and switch back when mains power returns.

Overview
An auto mains failure (AMF) panel watches the incoming mains supply. When it fails, the panel starts the diesel generator, transfers the load once the DG is ready, and transfers it back when mains power returns, then stops the DG after a cooling period.
We build AMF panels to suit your DG set and load, as standalone panels or as part of a DG-and-mains distribution line-up.
Key features
- Automatic DG start and stop on mains failure and restoration
- Interlocked changeover between mains and DG
- DG controller with engine protection and metering
- Manual, auto and test modes
- Can be combined with distribution and APFC sections
