Product Description
. . . . . Easy-to-adjust mechanical stop to limit damper rotation. Cut labor costs with simple direct coupling. Actuator Centers on 1/2" shaft. Clockwise or counterclockwise fail-safe mounting for fail-safe. Compact size with the shortest shaft center to edge distance in the industry - 0.77". True mechanical spring return - the most reliable fail-safe. Single line voltage model for on/off application has 100 to 240V (-15/+10%), 50/60 Hz supply power. 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).Rugged housing withstands rough handling in the mechanical room. 3 ft. standard cable and conduit connector (not shown) eases installation. The TF120 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 TF 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.. Belimo. Belimo. TF120 US.
