Si24SB4-30V-20A-AP1 The Si24SB4-30V-20A-AP1 is a 30V 20A, microprocessor based, high-power, Smart H-Bridger with a small (4.0”x3.3”x0.062”) Aluminum Plate Heat Sink and with user selectable Soft-Start and Soft-Stop features. This controller uses a single (9V to 30V at 0 to 20A) DC power supply to control the speed of a DC motor (or load-current) 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). 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 (Soft Select) motor

Si24SB4-50V-20A-AP1 The Si24SB4-50V-20A-AP1 is a 50V 20A, microprocessor based, high-power, Smart H-Bridger with a small (4.0”x3.3”x0.062”) Aluminum Plate Heat Sink and with user selectable Soft-Start and Soft-Stop features. This controller uses a single (9V to 50V at 0 to 20A) DC power supply to control the speed of a DC motor (or load-current) 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). 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 (Soft Select) 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).

Si30HFHB-50V-22A-HPC The Si30HFHB-50V-22A-HPC is a 50V 22A, microprocessor based, high-frequency, H-Bridge with high-pulse (0 to +5V PWM) control input. This board uses a single (9V to 50V at 0 to 22A) DC power supply to control the speed of a DC motor (or load current) in forward or reverse direction. An onboard microprocessor samples the control inputs at 150kHz rate and generates the timing signals for the H-Bridge. The high sampling rate provides a worst-case control latency of 7uS when the bridge is changing current direction or switching on or off. Two (0 to +5V) control signals (VI1,G and VI2,G) or switches are used to select the Stop/Go (pin I1) and motor direction (pin I2). The pin I1 input can be Pulse Width Modulated (PWM) from DC to 20kHz carrier rate.

Si30HFHB-50V-30A-AHC The Si30HFHB-50V-30A-AHC is a 50V 30A, microprocessor based, high-frequency, H-Bridge with active-high (0 to +5V) control inputs. This board uses a single (9V to 50V at 0 to 30A) DC power supply to control the speed of a DC motor (or load current) in forward or reverse direction. An onboard microprocessor samples the control inputs at 150kHz rate and generates the timing signals for the H-Bridge. The high sampling rate provides a worst-case control latency of 7uS when the bridge is changing current direction or switching on or off. Two active high digital (0 to +5V) control signals (VI1,G and VI2,G) or switches are used to select the direction of rotation (or Load-Current Direction). These inputs can be Pulse Width Modulated (PWM) from DC to 20kHz carrier rate.

Si30HFHB-50V-30A-ALC The Si30HFHB-50V-30A-ALC is a 50V 30A, microprocessor based, high-power, High-Frequency H-Bridge with active-low control inputs. This board uses a single (9V to 50V at 0 to 30A) DC power supply to control the speed of a DC motor (or load current) in forward or reverse direction. An onboard microprocessor samples the control inputs at 150kHz rate and generates the timing signals for the H-Bridge. The high sampling rate provides a worst-case control latency of 7uS when the bridge is changing current direction or switching on or off. Two active low digital (0 to +5V) control signals (VF,N and VR,N) or switches are used to select the direction of rotation (or Load-Current Direction). These inputs can be Pulse Width Modulated (PWM) from DC to 20kHz carrier rate.
