Ideal for the on/off, fail-safe damper control in HVAC systems, this BELIMO spring return damper actuator (120VAC) can provide true spring return operation for reliable fail-safe application and positive close off on air tight dampers. The spring return system provides a consistent torque to the damper with, and without, power applied to the actuator. Unit provides up to 95° of rotation and has a graduated position indicator displaying 0° to 95°. The actuator may be stalled anywhere in its normal rotation without the need for mechanical end switches, and it’s double insulated so an electrical ground connection is not required. Model comes with a built-in s SPDT switch for safety interfacing or signaling (for example, in fan start-up), and it’s adjustable between 0° and 95°.<br /><br /> Item: Spring Return Damper Actuator, 120VAC<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 /> Switch Type: SPDT<br /> Signal Type: On/Off<br /> Motor Direction: CW or CCW<br /> Ambient Temp.
