G122-826-001 Mobile P-I Servo Amplifier


The G122-826-001 is a general purpose, user configurable P-I Servoamplifier with a power supply input filter. It is specially designed with robust protection against harsh automotive power supply environments. Selector switches inside the amplifer enable proportional control, integral control, or both to be selected. Front panel trimpots, LED indicators, and test points allow easy setup, convenient troubleshooting, and flexibility for many applications.
