DC BRUSH TYPE SERVO AMPLIFIERS
DC4Q Series PWM servo amplifiers are designed to drive brush type DC motors at a high switching frequency. Operating efficiency is 95%. Seven LEDs and a relay output indicate the operating status. DC4Q servo amplifiers can easy interface with digital controllers or can be used as stand-alone drives. Loop gain, maximal current, nominal voltage and command signal weight can be adjusted by single-turn potentiometers. The offset adjusting potentiometer can also be used as an on-board input signal for testing purposes when a jumper is ON. DC4QR servo amplifiers have built-in rectifier and shunt-regulator, so they require a single AC power supply (single or three phase).
