These compact but powerful, direct-coupled (nonfail-safe) ControlSet® actuators provide tri-state/twoposition or proportional control for small dampers or valves in HVAC systems. A minimum torque of 40 (MEP-40xx) or 80 (MEP-48xx) in-lb. is available over the 95° angular rotation.
MEP-4xx2 proportional models accept a 2–10 VDC control signal input from a thermostat or controller. “Anti-jitter” circuitry significantly reduces hunting and needless wear (from unnecessary miniscule position changes caused by undamped analog input signals) on the actuator and valve packing or damper components. A user-initiated, auto-mapping feature provides more precise equipment control by reassigning the 2–10 VDC input signal range over a reduced rotation range (from 45° to 95°). These models also feature a switch-selectable, 1–5 or 2–10 VDC voltage feedback output that is proportional to the actuator position.
MEP-4xx1/4xx3 tri-state/two-position (three-wire) models are designed for use with floating thermostats, controllers, or building automation systems. The MEP-4x13 models feature a 10K ohm (± 10%), three-wire potentiometer feedback output. (The tri-state MEP-4003/4003V do not have two-position functionality or the larger green top enclosure.)
MEP-4x21/4x22 models also have a fully adjustable, built-in SPDT auxiliary switch, for remote position indication or controller and equipment interface.
MEP-4001V/4002V/4003V actuators have brackets with a patent-pending, quick-mounting mechanism. See (Quick-Mounting) “V” Models Valve Cross-Reference on page 4 for more information.
All other actuators mount directly to 1/4- to 5/8- inch (6 to 16 mm) round shafts or 1/4- to 7/16-inch (6 to 11 mm) 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 actuator.
- MEP-4xx2 proportional models include “antijitter” circuitry, optional auto-mapping of the full input signal range over a reduced actuator stroke, and switch-selectable voltage feedback
- MEP-4xx1/4xx3 tri-state/two-position (three-wire) models available (tri-state only on MEP-4003)
- Fully adjustable, built-in auxiliary switch on selected models
- Removable terminals and removable 1/2-inch NPS conduit fitting (except the MEP-4003)
- Direct mounting to standard shaft sizes
- Gear disengagement button and adjustable mechanical end stop
- Quick-mounting valve body option on MEP-4001V/4002V/4003V
