Belimo LMQ Series Non-Spring Return Damper Actuator

The LMQ quick running non-spring return actuators offers 35 in-lbs for approximately 8.5 square feet with running times of 7, 10, 15 or 20 seconds constant independent of load. The LMQ is for on/off and floating point control of dampers in HVAC systems. The GMB 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.
