PWM Input Trapezoidal Brushless Servo Amplifiers
30-125 VAC Input, 12.5A cont. (25A pk)@ 42-175 VDC Output
The BD25A20AC Series PWM servo amplifiers are designed to drive brushless DC motors at a high switching frequency. They are fully protected against over-voltage, over-current, over-heating and short-circuits. All models interface with digital controllers that have a digital PWM output. PWM IN determines the output duty cycle. DIR IN determines the direction of rotation. They require a single AC power supply. A single red/green LED indicates operating status. The current limit can be set by DIP switches.
