The Daikin-McQuay 1829709 Power Transistor Module is an electronic power-controlling component used to maintain electrical power supplied to powered equipment in HVAC systems. These electronic parts, called semiconductor switching transistors control and adjust the power signals they receive, allowing electricity to flow to motors and other parts in air conditioning and heat pump systems. It is installed in the equipment control compartment, and it is connected to the main control board and power wiring terminals. High-speed electronic switching regulates the flow of current to suit the requirements of the system, to allow steady operation of the motors.
