Description
The Schneider Electric (Barber Colman) MP-381 is a heavy-duty proportional actuator engineered for precise, reliable control in commercial HVAC and building automation applications. Delivering 220 lb-in of torque with a 180-degree rotation range, this non-spring-return actuator is well-suited for damper and valve control in demanding environments where accurate positioning is critical.
Key Features
- 24V operating voltage for compatibility with standard low-voltage control systems
- 220 lb-in torque output for reliable actuation of large dampers and valves
- 130-second timing (no load) for smooth, controlled positioning
- Non-spring-return design — holds last position on power loss
- SPDT auxiliary switch for end-of-travel signaling or auxiliary equipment control
- 180-degree rotation range for versatile application flexibility
- Proportional control for precise modulating operation
Application
The MP-381 is ideal for use in commercial HVAC systems, building automation, and industrial process control where proportional modulation of dampers or valves is required. The integrated SPDT auxiliary switch enables easy integration with control panels and monitoring systems.
