The BOE 300-030-2-5-1A Power Amplifier is a compact, high-precision current amplifier designed for the reliable control of electro-hydraulic servo valves in closed-loop control systems. Built by Schneider Servohydraulics, it delivers stable, repeatable valve control for demanding industrial, test, and servo-hydraulic applications.
This model is configured for 4–12–20 mA input signals and provides a rated valve current up to 300 mA, making it ideal for dynamic servo valve control where accuracy, responsiveness, and long-term reliability are critical.
Using a PWM H-bridge design with a high chopper frequency, the BOE 300-030-2-5-1A ensures smooth current regulation even in highly dynamic systems. Adjustable zero point, valve current, and dither settings allow precise matching to individual servo valves, improving control accuracy, reducing hysteresis, and extending valve service life.
Built into a 22.5 mm DIN-rail mount housing, the amplifier is compact, easy to install, and well suited to modern control cabinets. Integrated electronic protection safeguards the unit against short circuits and excessive temperatures, with automatic reset for reduced downtime.
