Available Torques of 177 lb‑in (20 N‑m) for Single Actuators, 354 lb‑in (40 N‑m) for Two Models, and 531 lb‑in (60 N‑m) for Three Models Mounted in Tandem
Microprocessor‑Controlled Brushless DC Motor (‑AGx, ‑GGx, and ‑HGx Types) Provides Constant Run‑Time Independent of Torque
Integral Auxiliary Switches (xxC Models) Provide One Fixed and One Adjustable Switch Point with Line Voltage Capability
Reversible Mounting Design Simplifies Installation and Enables the Actuator to Spring Return in Either Direction.
Integral 48 in (1.2 m) Halogen‑Free Cables with Colored and Numbered Conductors
Easy‑to‑Use Locking Manual Override with Auto Release and Crank Storage
Electronic Stall Detection throughout Entire Rotation Range
Removable Coupler Adapts to a Shorter Damper Shaft
Integral Connectors for 3/8 in Flexible Metal Conduit
NEMA 2 (IP54) Rated Aluminum Enclosure
The M9220‑xxx‑3 actuators are direct‑mount, spring‑return electric actuators that operate with these available power options:
AC 24 V at 50/60 Hz or DC 24 V (AGx, BGx, GGx, HGx)
AC 120 V at 60 Hz (BAx)
AC 230 V at 50/60 Hz (BDx)
These bidirectional actuators do not require a damper linkage, and are easily installed on dampers with 1/2 to 3/4 in. or 12 to 19 mm round shafts, or 3/8 and 1/2 in. or 10, 12, and 14 mm square shafts using the standard shaft clamp included with the actuator. An optional M9220‑600 Jackshaft Coupler Kit is available for 3/4 to 1‑1/16 in. or 19 to 27 mm round shafts, or 5/8 and 3/4 in. or 16, 18, and 19 mm square shafts. A single M9220‑xxx‑3 Electric Spring‑Return Actuator provides a running and spring‑return torque of 177 lb‑in (20 N‑m). Two or three models mounted in tandem deliver twice or triple the torque. Integral line voltage auxiliary switches are available on the ‑xxC models to indicate end‑stop position or to perform switching functions within the selected rotation range
