Actuator sizing should be done inaccordance with the damper manufacturer’s specifications.OperationThe actuator is not provided with and does not require any limit switches, but iselectronically protected against overload. The anti-rotation strap supplied with theactuator will prevent lateral movement.The LHQB(X) provides 4” [100 mm] of linear stroke. The stroke of the gear rack can beadjusted on both sides in increments of 0.8” [20 mm] by means of the mechanicalend stops.When reaching the damper or actuator end position, the actuator automatically stops.The gears can be manually disengaged with a button on the actuator cover.The LHQB(X)24-1-100 actuators use a sensorless brushless DC motor, which iscontrolled by an Application Specific Integrated Circuit (ASIC). The ASIC monitors andcontrols the actuator’s rotation and provides a digital rotation sensing (DRS) function toprevent damage to the actuator in a stall condition. Power consumption is reduced inholding mode.Dimensions (Inches [mm])LHQ24_1Technical DataLHQB(X)24-1-100Power supply24 VAC ± 20% 50/60 Hz24 VDC ± 20%Power consumption12 W (1.5 W)Transformer sizing18 VA (Class 2 power source)Electrical connectionLHQB24-1-1003 ft [1m]18 GA plenum rated cableprotected NEMA 2 (IP54)LHQX24-1-1003 ft [1m] 10 ft [3m] 16 ft [5m]18 GA plenum rated cableprotected NEMA 2 (IP54)Overload protectionelectronic throughout full strokeControlon/offInput impedance1000Feedback output U2 to 10 VDC (max 0.5 mA)VDC variableLinear stroke1.6” to 4.0” [40mm to 100 mm]Linear force22 lbf [100 Nm]Stroke directionreversible with switchManual overrideexternal push buttonRunning time3.5 seconds per 4” [100mm]Humidity5 to 95% RH non condensing (EN 60730-1)Ambient temperature-22°F to 122°F [-30°C to 50°C]Storage temperature-40°F to 176°F [-40°C to 80°C]HousingNEMA 2, IP54, UL enclosure type 2Housing materialUL94-5VAAgency listingscULus acc. to UL 60730-1A/-2-14, CAN/CSA E60730-1:02,CE acc. to 2004/108/EEC and 2006/95/ECNoise level (max)<52 dB(A)Servicingmaintenance freeQuality standardISO 9001Weight1.4 lbs [0.64 kg]† Rated Impulse Voltage 800V, Type of action 1.AA, Control Pollution Degree 3.40024 - 05/10 - Subject to change. © Belimo Aircontrols (USA), Inc.800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA346AccessoriesZ-DS1Rotary Support to Compensate Lateral ForcesZ-KSALinear CouplingP370Shaft Mount Auxiliary SwitchNOTE: When using LHQB(X)24-1… actuators, only use accessories listed on this page.Typical SpecificationOn/Off control damper actuators shall be electronic type, with integrated linearstroking arm.
