Description
The Schneider Electric (Barber Colman) MP-481-600 is a heavy-duty proportional actuator engineered for precise damper and valve positioning in commercial HVAC and building automation systems. Driven by a 1–15 Vdc input signal, this actuator delivers reliable modulating control with robust torque output and smooth, repeatable operation across its full 180-degree rotation range.
Key Features
- 120 V power supply for compatibility with standard commercial control circuits
- 220 lb-in torque output for driving large dampers and heavy-duty valves
- 130-second timing (no load) for smooth, controlled positioning
- Non spring return design — actuator holds its last position on power loss
- SPDT auxiliary switch for end-of-travel signaling or interlock control
- 180-degree rotation for wide-range damper and valve applications
- 1 to 15 Vdc proportional input drive for precise modulating control
