Description
The Schneider Electric (Barber Colman) MP-471 is a robust proportional actuator engineered for precise damper and valve control in commercial HVAC and building automation applications. Designed to deliver reliable, repeatable positioning performance, this actuator is a trusted choice for engineers and technicians who demand accuracy and durability in demanding control environments.
Key Features
- 120V supply voltage for compatibility with standard commercial control systems
- 50 lb-in output torque for dependable damper and valve actuation
- 90-second timing (no load) for smooth, controlled positioning
- Spring return counter clockwise (CCW) fail-safe operation for system safety on power loss
- SPDT auxiliary switch for end-of-travel signaling and external device control
- 180-degree rotation for broad damper and valve compatibility
- Proportional control for precise modulating response to control signals
Application
The MP-471 is ideal for use in commercial HVAC systems requiring modulating control of dampers, valves, and other final control elements. Its spring-return fail-safe mechanism ensures the actuator returns to the counter-clockwise position upon loss of power, protecting system integrity. The built-in SPDT auxiliary switch provides a convenient means of signaling end-of-travel position to a building automation system or other control device.
