AB50A100

The AB50A100 PWM servo drive is designed to drive brushless and brushed type DC motors at a high switching frequency. A single red/green LED indicates operating status.

The drive is fully protected against over-voltage, under-voltage, over-current, overheating and short-circuits across motor, ground and power leads. Furthermore, the drive can interface with digital controllers or be used stand-alone, and requires only a single unregulated DC power supply. Loop gain, current limit, input gain and offset can be adjusted using 14-turn potentiometers.

The offset adjusting potentiometer can also be used as an on-board input signal for testing purposes. This drive can use quadrature encoder inputs, Hall Sensors, or a tachometer for velocity control.
