AC power switching is accomplished using a proprietary technique which allows the controller to switch high current loads without sacrificing reliability. Because of the flexible architecture of this controller, design changes in timing cycles and current threshold levels can be easily accommodated without incurring excessive re-design charges. It controls DC power and cycle rate to de-ice propeller heater mats. The controller has fault monitoring which monitors heater mat current. If a fault is detected, the controller annunciates the pilot fault light and removes power from the load.
Power switching utilizes solid state technology to maintain high reliability.
This controller is an advanced propeller de-ice controller. It cycles 3-phase AC power to the propeller heater mats. AC power switching is accomplished using a proprietary technique which allows the controller to switch high current loads without sacrificing reliability.
