AMC China: Golden Ding Series Analog Drive CABH20A80

The CABH20A80 PWM servo drive is designed to drive brushless and brushed DC motors at a high switching frequency. T The CABH20A80 is fully protected against over-voltage, under-voltage, over-current, over-heating, invalid commutation, and short-circuits. A single digital output indicates operating status. The drive interfaces with digital controllers that have analog +/-10V output. The CABH20A80 can utilize either Hall Sensor or Tachometer feedback for velocity control.
