Description
Schneider Electric (Barber Colman) MP-485 Proportional Actuator Overview
The Schneider Electric (Barber Colman) MP-485 is a heavy-duty proportional actuator engineered for precise modulating control in commercial and industrial HVAC applications. With a built-in transformer, this actuator simplifies installation and reduces wiring complexity, making it a reliable choice for damper and valve control in building automation systems.
Key Features
- 120 V supply voltage for compatibility with standard commercial HVAC control circuits
- 220 lb-in output torque for dependable operation of large dampers and valves
- 130-second timing (no load) for smooth, proportional modulation
- Non spring return design — actuator holds last position on power loss
- SPDT auxiliary switch for end-of-travel signaling or auxiliary control functions
- 180-degree rotation for wide-range damper and valve positioning
- Built-in transformer eliminates the need for a separate external transformer
- Proportional (modulating) control for accurate positioning in response to a control signal
Application
The MP-485 is ideal for use in commercial HVAC systems requiring modulating control of air handling unit dampers, VAV systems, and control valves. Its high torque output and wide rotation angle make it well suited for large-area dampers and heavy-duty valve assemblies in building automation and energy management systems.
