Product Description

The td-805-h3 is a generator overvoltage relay for aircraft electrical systems. This protective component monitors system voltage and interrupts generator excitation when voltage exceeds safe operating limits, preventing damage to avionics and bus equipment. Installed in generator control units or three-unit regulator circuits, it stabilizes bus voltage by removing excitation during overvoltage conditions.

Installation requires verification of relay rating and pinout against the aircraft wiring diagram and applicable maintenance manual.

Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
