Description
The Schneider Electric (Barber Colman) MS51-7203-50 is a 24-volt spring-return damper actuator engineered for precise proportional control in commercial and industrial HVAC applications. Featuring a 0–10 VDC proportional control signal, this actuator delivers smooth, accurate positioning of dampers in air handling units, VAV systems, and building automation applications. The integrated manual override allows technicians to position the damper blade by hand during commissioning, maintenance, or power-loss scenarios — eliminating the need for additional tools or power.
Key Features
- 24V AC/DC supply voltage for broad system compatibility
- 0–10 VDC proportional control signal for precise modulating damper positioning
- Spring return (fail-safe) operation — returns to a defined safe position on power loss
- Integrated manual override for easy commissioning and maintenance
- Part of the Schneider Electric (Barber Colman) MS51 series actuator family
- Suitable for commercial HVAC, building automation, and air distribution systems
Application
The MS51-7203-50 is ideal for use in air handling units, mixing boxes, economizers, and VAV terminal units where reliable, modulating damper control is required. Its spring-return mechanism ensures fail-safe damper positioning in the event of a power interruption, making it well-suited for critical ventilation and energy management applications.
