Analog Input Trapezoidal Brushless Servo Amplifiers
30-125 VAC Input, 12.5A cont. (25A pk)@ 42-175 VDC Output
The BE25A20AC Series PWM servo amplifiers are designed to drive brushless DC motors at a high switching frequency. The BE25A20AC is fully protected against over-voltage, over-current, over-heating and shortcircuits. This model interfaces with digital controllers or can be used as a stand-alone drive and requires only a single AC power supply. A single red/green LED and a single digital output indicates operating status. 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, when SW1 (DIP switch) is ON.
