KMC Controls MEP-5233 Actuator

The KMC Controls MEP-5233 Actuator is a tri-state direct-coupled actuator designed for high-performance residential zoning. Engineered to provide 10 in-lb of torque, this 24VAC non-spring return motor is optimized for rectangular dampers with a 90-degree fully closed blade angle. As a verified M9101-AGA-2N2 direct replacement, it facilitates a seamless transition for legacy Johnson Controls systems without requiring extensive hardware modification. The unit features a rapid 15-second runtime for both opening and closing cycles, ensuring precise airflow management in VAV and residential air handling applications. With its 1/2-inch direct-coupled mounting and integrated manual disengagement feature, technicians can easily position the damper blade during commissioning. The durable, flame-retardant housing includes a position indicator and angular rotation stops, providing clear visual feedback and mechanical limits to prevent over-travel on HVAC damper replacements.

• Fast 15-Second Runtime: Delivers rapid response to thermostat calls, improving system efficiency and comfort.
• Direct Replacement Compatibility: Specifically designed to replace the M9101-AGA-2N2 in series B and C residential dampers.
• Simplified Installation: Features 1/2-inch direct-coupling and plated screw terminals for 14-22 AWG copper wiring.
• Manual Override: The disengagement button allows for manual positioning of the actuator and damper blade without power.
• Quiet Operation: Precision gearing ensures smooth, low-noise performance suitable for residential environments.

Is the MEP-5233 compatible with round dampers?
No, this model is designed for rectangular dampers with a 90-degree stroke. For round dampers requiring a 45-degree stroke, the MEP-5223 is the appropriate alternative.

What control signal does this actuator require?
The MEP-5233 utilizes a tri-state (floating) control signal and operates on a 24VAC Class 2 power supply.

Can I use this on Series A dampers?
This actuator is intended for replacement on Series B and C dampers only and is not compatible with Series A hardware.
