Description
KMC Controls MEP-7552 Proportional Spring Return Damper Actuator
The KMC Controls MEP-7552 is a heavy-duty, proportional spring return damper actuator engineered for reliable performance in commercial HVAC and building automation applications. Delivering 180 in-lb of torque at 24V, this actuator is well-suited for driving medium to large dampers in air handling units, VAV systems, and other HVAC control applications where precise, modulating control is required.
Key Features
- Supply voltage: 24V AC/DC
- Control type: Proportional (modulating) for precise positioning
- Torque output: 180 in-lb — handles medium to large damper loads
- Spring return (SR) fail-safe operation — returns to a defined position on power loss
- Runtime: 90–115 seconds for full stroke travel
- Designed for integration with KMC Controls building automation systems and compatible BAS platforms
- Suitable for commercial HVAC damper control in AHUs, VAV boxes, and mixed-air systems
Spring Return Fail-Safe Design
The spring return mechanism ensures the actuator automatically returns to its fail-safe position upon loss of power or control signal, providing critical protection for building systems and occupant comfort during power interruptions or system faults.
Proportional Control
The proportional (modulating) control signal allows for precise intermediate positioning of the damper blade, enabling accurate airflow regulation and improved energy efficiency compared to on/off actuators. This makes the MEP-7552 ideal for economizer control, mixed-air applications, and any system requiring continuous modulation.
