Designed for on/off, fail-safe control of dampers in HVAC systems, this BELIMO spring return damper actuator (24VAC/DC) mounts directly to a damper shaft from 3/8” up to 1/2” dia. using its universal clamp. Model can provide true spring return operation for reliable fail-safe application and positive close off on air tight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator. Actuator provides 95° of rotation and is provided with a graduated position indicator displaying 0° to 95°. The double-insulated actuator requires no ground connection and it may be stalled anywhere in its normal rotation without the need of mechanical end switches.<br /><br /> Item: Spring Return Damper Actuator, 24VAC/DC<br /> Mounting Type: Direct Mount<br /> Spring Return: Yes<br /> Shaft Type: 3/8" to 1/2" Round or 3/8" to 7/16" Square<br /> Torque: 35 in.-lb.<br /> Stroke Deg.: 0 to 95<br /> Height: 7-43/64"<br /> Width: 3-55/64"<br /> Depth: 3-15/64"<br /> Signal Type: On/Off<br /> Motor Direction: CW or CCW<br /> Ambient Temp.
