The Si5HyUdMCDF1-30V-20A is a 30V 20A, microprocessor based, Single, Closed-Loop, Hybrid, Unidirectional, Motor-Controller with an integrated heat sink and with a Digital Feedback port. This board uses pulse-width modulation (PWM) to efficiently control the speed of a brush type DC motor (or load current) in open or closed loop control mode in the 0 to 600W power range, and in 5W steps. The desired control mode is selected by a jumper (J1M). An open-circuit (no jumper) selects the open-loop mode, while short-circuit (jumper installed) selects the closed-loop mode. The desired motor speed (or load current) is set by a (0 to 5V) range external analog voltage (applied to I1 input pin on port CN4). The Si18V1RPM-Sens optical interrupter (connected to port CN3) along with Si18V1RPM-Wheel optical wheel (mounted on the motor shaft) provides proportional feedback, keeping the motor-shaft rotating at a constant speed. The speed-range is adjustable with an onboard 25-turn trim pot in the 50 to 3000 rpm range. This board requires a single 9V to 30V DC power source (unregulated and unfiltered) at a 0A to 20A current range to operate normally. An onboard microprocessor generates a 5kHz or 20kHz PWM carrier signal, controls the load-power (or motor speed) and monitors the sensor inputs. The PWM carrier frequency is user selectable by the jumper CN4, 20kHz when CN4 is open and 5kHz when short. The high frequency PWM rate provides a smooth motor-speed control, and insures a quiet motor environment. Typical applications are: DC Motor-Speed Controller, Light-Dimmer with variable delay, Power Amplifier, SPST Solid State Relay, etc.
