Power Supply / Amplifier

The Power Supply / Amplifier series consists of combined power supply and amplifier boards manufactured by MOOG. These boards provide regulated DC power output while amplifying control signals for servo motor systems, supporting precise motion control in industrial machinery.

Products in this family, such as the Moog 121-103 and 121-148, are commonly used in servo control applications and are found in paper manufacturing equipment and other industrial machinery. Boards in the series typically feature multiple output voltages with AC input through a barrier strip.
