Description
The Schneider Electric (Barber Colman) MS41-6153 is a heavy-duty, non-spring return (NSR) direct-coupled damper actuator engineered for precise modulating control in commercial HVAC and building automation applications. Accepting a 0–10 VDC control signal, this actuator integrates seamlessly with DDC systems and building automation controllers to deliver accurate, repeatable damper positioning across a wide range of air-handling and ventilation systems.
Key Features
- 24V AC/DC power supply for broad compatibility with commercial control systems
- Non-spring return (NSR) operation — damper holds last position on power loss
- 0–10 VDC modulating control signal for precise proportional positioning
- 133 lb-in (15 Nm) torque output handles large or high-resistance dampers
- Direct-couple mounting eliminates the need for crank arms or linkages
- Compact, low-profile housing for easy installation in tight mechanical spaces
- Manual override function for commissioning and maintenance convenience
