P176
Dimmer Power Supply

Product

The last dimmer power supply your aircraft will ever need.

The P176 Dimmer Power Supply is a direct replacement for the AS350 OEM Dimmer Power Supply including P/N 704A46814049 and earlier installed equipment. The P176 is the exact same footprint as the OEM unit, is plug compatible, and does not require any wiring changes or modifications for installation. In addition, because no spacers are required to mount the unit, installation is fast and painless for mechanics.

The P176 Dimmer Power Supply is also short circuit and thermally protected, eliminating costly repairs caused by electrical shorts. In the event of a short circuit, the Dimmer Power Supply will shut down as a precautionary measure and resume normal operation when the short is removed. There are no fuses to replace in the unit, as it is self-resetting.

Features

  • Direct replacement for OEM P/N 704A46814049
  • Short-circuit and thermal protected
  • Gold-plated contacts for the vertical header and edge connector
  • Conformal coated to prevent corrosion of the PCB
  • Linear design generates no radiated electromagnetic interference
