The Si5HyUdMC2-30V-2x16A is a 30V 2x16A, microprocessor based, Dual, Open-Loop, Hybrid, Unidirectional, Motor-Controller with an integrated heat sink that uses two independent pulse-width modulators (PWM) to efficiently control the speed of two brush type DC motors (or load currents ) each in the 0 to 480W power range, and in 4W steps. An onboard microprocessor generates two 5kHz or 20kHz PWM carrier signals, controls the load-power to each motor (or motor speeds) and controls the load-current rates (or acceleration and deceleration of each motor). The PWM carrier frequency is user selectable by the jumper CN4, both 20kHz when CN4 is open and both 5kHz when short. The high frequency PWM rate provides a smooth speed control to each motor and insures a quiet motor environment. As the name hybrid (Hy) implies, the desired motor speeds (or PWM pulse-durations) are set by two variable (0 to +5V) analog input-voltages VI1,G and VI2,G each providing a smooth motor-speed control from 0 to 100% in 0.83% steps; while the other control-signals are digital. These analog inputs (VI1,G and VI2,G) are zener-diode protected. The user can choose between both slow or both fast motor-acceleration/deceleration modes by short-circuiting or open-circuiting the pins labeled J1M. The slow mode, with rise-time/fall-time of 0.5s, is selected by short-circuit (J1M jumper installed); while the fast mode, with rise-time/fall-time of 0.025s, is selected by leaving these pins open (no Jumper installed). Two onboard LEDs are used to monitor the load-voltages. A small (2.3”x2.4”x0.45”) finned integrated heat sink is included with mounting hardware (as shown on the photograph) to operate at 960W power level. Higher power-levels (30V, 2x20A or 1200W) can be achieved with more efficient heat-sinks.
