Reversible and Proportional Electric Actuators
Model Chart
The MP Series Actuators are used for two-position,
floating, and proportional control of dampers,
valves, and program switches in heating,
ventilation, and air conditioning applications or
similar applications.
Features:
• Proportional actuators with built-in feedback
potentiometers.
• Spring return and non-spring return models available.
• 24 Vac, 120 Vac, and 240 Vac models are available.
• Die cast housings with four 1/2 in. conduit openings.
• Oil-immersed motor and gear train.

Units with a “-2” suffix, e.g. MP-xxxx-xxx-2-x, include a built-in transformer (used for Microtherm or with AE-504) with secondary loads
wired externally to terminals seven and eight of the actuator. Red (24 Vac) to terminal eight and Blue (12 Vac) to terminal seven. When
these actuators are used with controllers other than Microtherm or AE-504, disconnect the Red and Blue leads and tape off. Note: Models
prior to “-2” suffix had transformer wired directly to potentiometer. To disconnect the transformer, remove the back plate of the actuator,
disconnect, and tape the transformer leads.
