KMC Controls Direct-Coupled Spring-Return Fail-Safe Actuator, Proportional 2-10 VDC (45 in-lb)

Direct-Coupled Spring-Return Fail-Safe Actuator, Proportional 2-10 VDC (45 in-lb) These compact but powerful direct-coupled ControlSet® actuators provide two-position, tri-state, or proportional control for dampers or valves in HVAC systems. Efficient, durable, capacitor-driven fail-safe with switch-selectable direction provides consistent torque in both powered and fail-safe modes. A patent-pending noise reducer provides whisper-quiet operation in both modes. A minimum torque of 25 (MEP-42xx), 45 (MEP-45xx), or 90 (MEP-49xx) in-lb. is available over the 95° angular rotation. MEP-4xx2 proportional models accept a 2–10 VDC control signal input from a thermostat, controller, or building automation system. “Anti-jitter” circuitry significantly reduces hunting and needless wear (from unnecessary miniscule position changes caused by undamped analog input signals) on the actuator, valve, or damper components. A user-initiated, auto-mapping feature provides more precise equipment control by reassigning the 2–10 V...
