Belimo LU Series Non-Spring Return Damper Actuator

The LU non-spring return actuators offers 27 in-lbs for approximately 6 square feet for on/off and floating point control of dampers in HVAC systems. The LU actuators use a brushless DC motor, which is controlled by an Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the actuator’s rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in holding mode.
