Product Features:

Over-Voltage Protection

The OV Protector (OVP) or OV Relay deactivates the Voltage Regulator by removing power to its input if the bus voltage exceeds 32V. This removes excitation from the alter-nator and thus protect sensitive avionics equipment and the battery.

Counter-EMF protected Relay

The OV Relay is a normally closed switch which opens when the bus voltage exceeds 32V. It has a time delay that prevents nuisance tripping caused by system noise or voltage spikes. The regulated bus voltage is normally about 28V unless the alternator is self-current limiting1 or if there is voltage drop in the alternator field circuit breaker, alternator switch, OV Relay, or wiring and connections between the bus and the red wire on the VR. These voltage drops across the different components and connections occur when cur-rent, up-to 3 Amps in some instances, passes through the resistance built-up in them. The resistance build-up causes flickering ammeter and instrument panel lights.

Other Features:

  • Integrated Circuit OV sensor
  • Protects system against overexcited alternator field
  • Increase the life of the OV Relay
  • Less temperature sensitive and more precise.
