Generator Controls:

Digital generator control module (GCM) features voltage regulation, generator fault protection, and a generator operating parameter display. The GCM monitors the 400 Hz output when 400 Hz is in use and automatically switches over to monitor 28.5 VDC output when optional 28.5 VDC transformer rectifier is in use. The voltage regulator provides line drop compensation on 400 Hz as well as line drop compensation and current limiting on optional 28.5 VDC transformer rectifier. The GCM displays the generator output operating parameters such as voltage, current, and frequency digitally on a backlit LCD. The GCM is programmed to provide generator output fault protection in the following settings:

  • Over frequency: 420 Hz in 5 seconds
  • Under frequency: 380 Hz in 7 seconds
  • Over voltage: 130 volts in 2 seconds
  • Under voltage: 100 volts in 7 seconds
  • Overload: 125% of rated load for 5 minutes
