These powerful, efficient, durable, direct-coupled actuators provide tri-state or proportional control for large control air dampers or valves in HVAC systems. A minimum torque of 180 or 320 in-lb. is available over the 94° angular rotation. Capacitor-driven fail-safe models provide durable, efficient operation with switch-selectable fail direction.

The proportional actuator models accept a 2â 10 VDC or 4â 20 mA control signal input from a thermostat, controller, or building automation system. "Anti-jitter" circuitry significantly reduces hunting and needless wear on the actuator and valve packing or damper components (from unnecessary miniscule position changes caused by undamped analog input signals). A user-initiated, auto-mapping feature provides more precise equipment control by reassigning the (2â 10 VDC or 4â 20 mA) input signal range over a reduced rotation range (from 45¬∞ to 94¬∞). These models also feature a switch-selectable, 1â 5 or 2â 10 VDC voltage feedback output that is proportional to the actuator position.

The tri-state models are designed for use with floating thermostats, controllers, or building automation systems. They feature an optional 10K ohm (±10%), three-wire potentiometer feedback output. Fail-safe models also allow two-position control as well.

All actuators mount directly on 3/8" up to 1.05" round or 5/16" up to 5/8" square shafts, eliminating the need for expensive and complicated linkages. A non-rotation bracket, to prevent lateral movement, is included with each actuator. A gear disengagement button allows manual positioning of the damper and/or gear train without energizing the actuator. Removable terminals and 1/2" NPS conduit fittings make wiring easier. The actuators are protected against overloading and do not require end or limit switches.

(If lower torque is required, see also the MEP-4200/4500/4900 series.)
