Bray’s wide variety of commercial electric actuator choices increases flexibility when choosing peripheral products for Building Automation Systems. We offer many different torque outputs and optional features to ensure you have the best actuator for the application. Jumper or DIP switch selectable features allow versatility in the field. The actuators are maintenance-free, which means fewer call backs after installation and start-up. In addition, our actuators are manufactured to ISO 9001 and Six Sigma Standards making them the highest quality on the market today.  

The D(M)S24-180 Series Electric Actuators are direct-mount, spring return electric actuators that operate on AC/ DC 24V power. 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 M9220-6 00 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 D(M)S24-180 Series Electric Spring Return Actuator provides a running and spring return torque of 17 7 lb·in (20 N·m). Two or three like models mounted in tandem deliver twice or triple the torque (354 lb·in [40 N·m] or 531 lb·in [6 0 N·m]). I ntegral line voltage auxiliary switches are available on the -A models to indicate end-stop position or to perform switching functions within the selected rotation range.
