Electric Spring Return Actuator With Proportional Control For Dampers 24 VAC M9220 GGA 3 Series Electronic Stall Detection Throughout Rotation Removable Coupler For Shorter Shaft Halogen Free Cables 1.2 Meter
UPC:
✔️ 24 VAC operation with stall detection and removable coupler
Electric spring-return actuator designed for HVAC dampers and building ventilation systems. It provides proportional control for precise damper positioning and includes electronic stall detection to protect the motor against overload.
✅ Electronic Stall Detection throughout rotation range to deactivate the motor on overload.
✅ Removable Coupler adapts to shorter damper shafts.
✅ Integral 48 in (1.2 m) Halogen-Free Cables with Colored and Numbered Conductors for easy field wiring.
✅ NEMA 2 (IP54) Aluminum Enclosure protects internals from dirt and moisture.
✅ Easy-to-Use Locking Manual Override with Auto Release and Crank Storage.
✅ Bidirectional actuator fits dampers with 1/2-3/4 in (12-19 mm) round shafts or 3/8-1/2 in (10-14 mm) square shafts using the included shaft clamp.
✅ Optional M9220-600 Jackshaft Coupler Kit for 3/4-1-1/16 in (19-27 mm) round shafts or 5/8-3/4 in (16-19 mm) square shafts.
✅ One M9220-xxx-3 provides 177 lb-in (20 N·m) torque; two or three units in tandem deliver twice or triple the torque.
✅ Integral line voltage auxiliary switches available on the -xxC models to indicate end-stop position or perform switching within the rotation range.
💡 What is an electric spring-return actuator used for in damper control?
It is a handy device for moving HVAC dampers to a set position and returning to that position when power is removed. This makes it easy to maintain safe and predictable airflow in ductwork.
- Provides reliable damper positioning with proportional control for precise air flow
- Returns to a safe position on power loss
- Electronic stall detection protects the motor from overload
- Removable coupler and 1.2 m halogen-free cables simplify wiring in the field
