The LF series actuators provide true spring return operation for reliable fail-safe application and positive close off on airtight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator. The LF series provides 95° of rotation and is provided with a graduated position indicator showing 0° to 95°. The actuator may be installed anywhere in its normal rotation without the need of mechanical end switches. Power consumption is reduced inholding mode. The actuator is double insulated so an electrical ground connection is not necessary. The LF120-S US version are provided with one built-in auxiliary switch. This SPDT switch is provided for safety interfacing or signaling, for example, for fan start-up. The switching function is adjustable between 0° and 95°.
