Hoffman Controls 792-ECM Controller 318423-701 Common Questions: What are theThe Hoffman Controls 792 ECM Controller is a professional grade solution for modulating the speed of high efficiency ECM brushless DC motors. Engineered for variable air volume (VAV) applications, this ECM speed controller provides precise proportional speed control based on a 2 10VDC or 4 20mA DC input signal. It is line voltage independent, requiring only a 24VAC power source, and utilizes pulse width modulation (PWM) at 80Hz to regulate motor RPM
