10A8DD

The 10A8DD PWM servo amplifier is designed to drive brush type DC motors. The PWM frequency is determined by the PWM input signal. It is fully protected against over-voltage, over-current, over-heating and short circuits across motor, ground and power leads. This model interfaces with digital controllers that have a digital PWM output. It can also be used as a stand-alone system . The 10A8DD amplifier requires only a single unregulated DC power supply as all logic and control voltages are generated internally. PWM input determines the output duty cycle. "Direction In" determines which side of the "H bridge" output is switching. The current limit can be reduced by an external resistor. The voltage at the current monitor pin P1-11 is proportional to the actual motor current.
