Description for Belimo LF24-S

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.
  • 3 ft. cable and conduit connector eases installation.
The LF24-S 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.
