Spring Return Fail-Safe, On/Off Damper Control Actuator, Direct Coupled - 120 VAC (No Aux Switch)

Description:

3 ft. cable and conduit connector included to ease installation. The LF120 is used for On/Off, fail-safe control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer's specifications. Control is On/Off from an auxiliary contact, or a manual switch. The LF series actuators 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. Features: Cut labor costs with (10 min. installation) simple direct coupling. Actuator Centers on 1/2" shaft (K6-1, 3/4" clamp optional). True mechanical spring return - the most reliable failsafe. Mount for clockwise or counterclockwise fail-safe. Easy-to-adjust mechanical stop to limit damper rotation. Check damper position easily with clear position indicator. Don't worry about actuator burn-out. Belimo is overload-proof throughout rotation. Need to change control direction? Do it easily with a simple switch (modulating actuators). Built-in auxiliary switch is easy to use, offers feedback or signal for additional device. Microprocessor-controlled brushless DC motor increases actuator life span and reliability, provides constant running time (modulating actuators). Provided on Basic Models Rugged metal housing withstands rough handling in the mechanical room.
