Description
The Mitsubishi Electric U01A44451 Inverter PC Board is an electronic control board that is supposed to regulate the inverter drive operations in HVAC systems. This is used to regulate variable frequency to compressors and fans to allow the speed to be finely adjusted to provide better part-load operation. It controls the delivery of power based on temperature, load, and demand signals acting on the line voltage of the unit and communicating with sensors and user controls. This is placed in outside condensers and enables the capacity, airflow, and system response to be modulated effectively during the heating and cooling cycles.
