Introduction :
The Rhino Dual Driver 20A enables bidirectional control of two high-power brushed DC motors from 6V to 30V. With full discrete NMOS H-
Bridge design, this motor driver is able to support 20Amp continuously for each motor without any heat-sink
The onboard test buttons and motors output LEDs allow functional test of the motor driver in a quick and convenient way without hooking up
the host controller. This motor driver can be controlled with PWM and DIR inputs.
it's compatible with wide variety of host controller (e.g. Arduino, Raspberry Pi, PLC).
The advantage of this drive is that all inputs are electrically and optically isolated.
Various protection features are also incorporated in each channel of the Rhino 20A. Over-current protection prevents the motor driver from
damage when the motor stalls or an over-sized motor is hooked up. When the motor is trying to draw current more than what the motor
driver can support, the motor current will be limited at the maximum threshold.
Assisted by temperature protection, the maximum current limiting threshold is determined by the board temperature. The higher the board
temperature, the lower the current limiting threshold. This way, Rhino Dual Driver 20A able to deliver its full potential depending on the
actual condition without damaging the MOSFETs.
Note: Power input does not have reverse-voltage protection. Connecting the battery in reverse polarity will damage the motor driver
instantaneously.
