The SPUU-52 is an aircraft control system designed to provide movable mechanical stops for regulating and limiting control parameters in onboard aircraft systems.

Within the control architecture, the system converts electrical input signals into controlled mechanical displacement of adjustable stops, ensuring precise limitation and stabilization of regulated parameters within the specified operating range.

The system is applied in aircraft control and regulation circuits where coordinated limitation by temperature and pressure parameters is required as part of automatic control loops.

The product is also known under alternative designations SPUU-52, СПУУ-52, which refer to the same product type.
