Actuator sizing should bedone in accordance with the damper manufacturer’s specifications.The actuator operates in response to a 2 to 10 VDC, or with the addition of a500 resistor, a 4 to 20 mA control input from an electronic controller or positioner. AA 2 to 10 VDC feedback signal is provided for position indication or master-slaveapplications.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 LHB(X)24-SR... series provides 4 or 8 in of linear stroke. The stroke of the gearrack can be adjusted on both sides in increments of 0.8 in [20 mm] by means of themechanical end 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 LHB(X)24-SR… 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]).69"[17.4].54"[13.7]2.64"[67]AABB3" [75]2" [50.8]1.1"[27.8]2.6"[66].16" [4]0.13" [3.2]Stroke A4" [100]9.2" [233.5]8" [294.2]8" [200]13.1" [333.5]12" [394.2]135Technical DataLHB(X)24-SR(-100)(-200)Power supply24 VAC ± 20% 50/60 Hz24 VDC ± 20%Power consumption1.5 W (0.5 W)Transformer sizing3 VA (Class 2 power source)Electrical connection18 GA appliance rated cable1/2” conduit connectorprotected NEMA 2 (IP54)3 ft [1m] 10 ft [3m] 16 ft [5m]Overload protectionelectronic throughout full strokeControl2 to 10 VDC, 4 to 20 mAInput impedance100 k (0.1 mA), 500 Feedback output U2 to 10 VDC (max 0.5 mA)Linear strokeLHB(X)24-SR-1004 in [100 mm]LHB(X)24-SR-2008 in [200 mm]Linear force34 lbf [150 N]Stroke directionreversible with switchactuator will move in the selected directionwith increasing control signal (2 to 10V)Manual overrideexternal push buttonRunning time150, 95, or 75 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)35dB(A)Servicingmaintenance freeQuality standardISO 9001WeightLHB(X)24-SR-1000.81 lbs [0.37 kg]LHB(X)24-SR-2000.86 lbs [0.39 kg]† Rated Impulse Voltage 800V, Type of action 1, Control Pollution Degree 3.40024 - 05/10 - Subject to change. © Belimo Aircontrols (USA), Inc.800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA340AccessoriesZ-DS1Rotary Support to Compensate Lateral ForcesZ-KSALinear CouplingP370Shaft Mount Auxiliary SwitchSGA24Min Positioners in NEMA 4 HousingSGF24Min Positioners for Flush Panel MountingPTA-250Pulse Width Modulation InterfaceIRM-100Input Rescaling ModuleADS-100Analog to Digital SwitchZG-R01Resistor for 4 to 20 mA ConversionNSV24 USBattery Back-Up ModuleZG-X40TransformerNOTE: When using LHB(X)24-SR… actuators, only use accessories listed on this page.Typical SpecificationProportional control damper actuators shall be electronic type, with integrated linear stroking arm.
