Description
The Schneider Electric (Barber Colman) MP-461 is a commercial-grade proportional actuator engineered for precise damper and valve control in building automation and HVAC systems. Operating on 120V power with a 2–12 VDC proportional control signal, this actuator delivers accurate, modulating positioning to maintain optimal system performance across a wide range of commercial applications.
Key Features
- 120V operating voltage for compatibility with standard commercial HVAC control circuits
- 2–12 VDC proportional input signal for smooth, modulating control response
- 50 lb (50#) actuator force for reliable authority over dampers and valves
- Span/Range (S/R) adjustability for flexible field calibration
- Part of the trusted Schneider Electric (Barber Colman) MP Series actuator family
- Designed for building automation, VAV, and commercial HVAC control systems
Specifications
- Brand: Schneider Electric (Barber Colman)
- Model: MP-461
- Supply Voltage: 120V
- Control Signal: 2–12 VDC Proportional
- Actuator Force: 50 lb
- Signal Type: Span/Range (S/R)
