KMC Controls MEP-4802 Actuator
The KMC Controls MEP-4802 is a professional-grade, 24VAC non-spring return actuator designed for the precise modulation of small dampers and valves in commercial HVAC systems. Delivering a minimum 80 in-lb torque (9 N?Çóm), this unit is the go-to choice for contractors requiring higher force than standard 40 in-lb models without upgrading to larger, bulkier footprints. Operating on a 0-10 VDC control signal, the MEP-4802 features advanced anti-jitter circuitry, which actively filters undamped analog input signals to prevent hunting, thereby reducing mechanical wear on damper seals and valve packings.
Built for direct-coupled installation, the MEP-4802 eliminates the need for complex linkages by mounting directly to 1/4" to 5/8" round or 1/4" to 7/16" square shafts. The 90-second runtime ensures stable modulating control, while the user-initiated auto-mapping feature allows for calibrating the full signal range over a reduced rotation (from 45?? to 95??). With its NEMA 2 / IP54 housing and wide operating temperature range (-22??F to 131??F), this damper actuator provides the long-term reliability required in demanding building automation architectural environments.
Key Benefits
- Precision Modulation: Optimized for 0-10 VDC or 2-10 VDC inputs with switch-selectable voltage feedback for real-time position tracking via the BAS.
- Reduced Mechanical Fatigue: Integrated anti-jitter technology prevents unnecessary micro-adjustments caused by noisy control signals.
- Efficient Installation: Features a gear disengagement button for manual positioning and a removable 1/2" NPS conduit fitting for streamlined wiring.
- Versatile Compatibility: Mounts directly to various shaft shapes and sizes; compatible with VFB-43 and VFB-46 series valve bodies using standard brackets.
Common Questions
Does this unit return to a fail-safe position upon power loss?
No, the MEP-4802 is a non-spring return (non-fail-safe) model. It will maintain its last position if 24VAC power is interrupted. For fail-safe applications, consider the MEP-4200 or MEP-4500 series.
Can I adjust the rotation limits for smaller dampers?
Yes, the actuator includes an adjustable mechanical end stop and a software-based auto-mapping feature that reassigns the full 0-10V control signal across a shorter stroke.
How do I reverse the acting direction (DA/RA)?
The MEP-4802 includes a physical slide switch inside the wiring compartment to easily toggle between clockwise (CW) and counter-clockwise (CCW) operation without re-wiring the input signal.
