Si24HyBdMC1-50V-20A-AP1

$229.00
The Si24HyBdMC1-50V-20A-AP1 is a 50V 20A, microprocessor based, high-power, Hybrid, Bidirectional, Motor Controller with user selectable Soft-Start and Soft-Start features. This board is mounted on the AP1 Heat Sink, and uses a single (9V to 50V at 0 to 20A) DC power supply to control the speed of a DC motor in forward or reverse direction. An onboard microprocessor generates a 5kHz or 20kHz PWM carrier signal, controls the load-power (or motor speed), controls the load-current rate (or motor acceleration and deceleration), updates the Liquid Crystal Display (LCD) and monitors the user inputs. The PWM carrier frequency is user selectable by the jumper J2, 20kHz when J2 is open and 5kHz when short. This high frequency PWM rate insures a quiet motor environment. The user can choose between slow or fast motor acceleration/deceleration modes by short-circuiting or open-circuiting the pins labeled J1. The slow mode, with rise-time/fall-time of 1.25Sec, is selected by short-circuit (J1 jumper installed); while the fast buildup mode, with rise-time/fall-time of 0.05s, is selected by leaving these pins open (no Jumper installed). As the name hybrid (Hy) implies the required motor speed (or PWM pulse-duration) is variable from 0 to 100% in 0.83% steps using the analog voltage (VI1,G=0V=0%PWM, VI1,G=+5V=100%PWM,), while the motor direction is selected using two active low digital (0 to +5V) control signals (VF,N and VR,N) or switches.
