The MP-361 actuator by Schneider Electric is designed for precise control over dampers and globe valves. With a torque capacity of 50 lb-in (5.6 N-m), this device is robust enough to handle various demanding applications. It operates on a 24 Vac power supply at a frequency of 60 Hz, consuming a maximum current of 2.5 A.
Control signals are proportional, ranging from 2 to 12 Vdc, enabling compatibility with Barber-Colman Microtherm systems. In case of a power loss, the actuator automatically returns to a clockwise position, ensuring safety and functionality. Under normal conditions, it has a no-load timing of roughly 90 seconds. The actuator offers a versatile angle of rotation, which is adjustable from 45° to 320°, with a nominal value of 180°.
The device includes one single-pole double-throw (SPDT) auxiliary switch, enhancing its functionality. Electrical connections are made via screw terminals for secure installation. The enclosure is rated NEMA 1, suitable for indoor use.
Regarding temperature performance, the MP-361 can function effectively in a range from -40°C to 58°C, withstanding storage temperatures of -40°C to 71°C. This broad thermal range ensures reliable operation across varied environments.
