Automatic Mains Fail Panels (AMF)

Our AMF panels are specified by the size in amps and the required control module, new control module updates are released regularly so please enquire if you do not see the configuration or manufacturer you require.

All panels use the highest quality switch gear and can be amended to your specification. Please note additions' may require a larger enclosure.

  • Mechanically & electrically Interlocked pair of contactors or ACB’s
  • Miniature circuit breakers used for protection circuits
  • Generator interface terminals
  • 3 Phase mains monitoring
  • Single or three phase generator voltage monitoring
  • Configurable timers
  • Robust mild steel enclosure
  • Bottom entry gland plate

  • Wall mounted or free standing enclosures

WHAT IS AN AMF PANEL & HOW DOES IT WORK

Automatic Mains Fail panels are used where the local utility mains supply is backed up by an appropriately sized generator. The AMF panel monitors the local mains supply; if this supply should fail, or fall outside preset limits the AMF panel will control the pre-heating, fuel solenoid and starting of the generator. The AMF panel will then control the switching of the load from the local supply to the generator. Whilst the generator is running the AMF panel will monitor vital engine and alternator parameters safely stopping the generator should a fault condition occur. On return of the local supply the AMF panel will monitor the Supply to ensure it is stable and then transfer the load from the generator back to the local supply. The AMF panel will run the generator on for a pre-determined time to allow for any cool down periods required for the generating set. Once this time has elapsed the AMF panel will control the stopping of the generator.

All our AMF panels use the latest microprocessor controlled modules to enhance and provide maximum functionality. Various timers are included in the controller to prevent nuisance starting of the generator due to minor breaks in the local supply.

AMF panels are located at, and fitted to, the generator. If this does not fit with your infrastructure and wish for generator control to be located away from the site of the generator then a suitable Automatic Transfer Switch is a better option.
