Models 30A20AC, 16A20AC
Analog Input Brush Servo Amplifiers
30-125 VAC Input, 8A-15A cont. (16A-30A pk)@ 42-175 VDC Output
The 30A-AC Series PWM servo amplifiers are designed to drive brush type DC motors at a high switching frequency. A single red/green LED indicates operating status. All models are fully protected against over-voltage, over-current, over-heating and short-circuits across motor, ground and power leads. These models interface with digital controllers or can be used as a stand-alone system. They require only a single AC 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 when SW10 (DIP switch) is ON.
