KMC Controls MEP-7502 Actuator

For high-demand air handling units and large damper control, the KMC Controls MEP-7502 provides the 180 in-lb torque required for precise proportional damper actuator performance. Operating on 24VAC/DC, this non-spring return actuator is the designated MEP-1262 direct replacement, engineered to handle heavier loads with more consistent timing than its 7000-series predecessors. The integrated anti-jitter circuitry is a critical feature for contractors, as it eliminates the hunting and rapid micro-adjustments often triggered by undamped 0-10 VDC or 4-20 mA control signals, significantly reducing wear on your damper seals and gear trains.

The MEP-7502 is built for rapid field installation, featuring a direct-coupled mounting design that secures to round shafts up to 1.05 inches or square shafts up to 5/8 inches using a robust V-bolt assembly. Its auto-mapping capability allows for a user-initiated calibration of the full signal range over a reduced stroke for specific cfm requirements. With a NEMA 2 housing and a temperature rating down to -22??F, this unit is a reliable choice for commercial HVAC building automation applications where high torque and modulating precision are non-negotiable.

• High-Torque Performance: Delivers a consistent 180 in-lb (20 N-m) of torque, suitable for large dampers and valves.
• Universal Control Compatibility: Accepts 0-10 VDC, 2-10 VDC, or 4-20 mA analog signals for seamless integration into any BAS.
• Anti-Jitter Technology: Proprietary circuitry stabilizes the actuator response, preventing premature failure due to signal noise.
• Simplified Wiring: Features removable terminal blocks and dual 1/2-inch NPS conduit fittings for efficient field termination.
• Manual Override: A gear disengagement button allows for manual shaft positioning during commissioning or emergency service.

Is the MEP-7502 compatible with my older MEP-1262 wiring?
Yes, the MEP-7502 is the direct functional replacement for the MEP-1262. It maintains the same torque profile and proportional input requirements, though the terminal layout may vary slightly; always verify your common and signal wires against the new terminal block labels.

What does the auto-mapping feature do?
If your damper stroke is limited (e.g., only 60 degrees of rotation), auto-mapping re-scales the full 2-10 VDC input signal across that limited range, ensuring you maintain full resolution and precision over the available travel.

Does this unit require end switches to prevent motor burnout?
No. The MEP-7502 is electronically protected against overloading and does not require limit switches; it will simply stall at the end of its travel without damage to the motor or gear train.
