Electrical data Nominal Voltage: AC/DC 24 V Nominal Voltage Frequency: 50/60 Hz Nominal Voltage Range: AC 19.2...28.8 V / DC 19.2...28.8 V Power Consumption in Operation: 2.5 W Power Consumption in Rest Position: 0.4 W Power Consumption for Wire Sizing: 4.5 VA Connection Supply / Control: Cable 1 m, 4x 0.75 mm² Parallel Operation: Yes (note performance data) Functional data Actuating Force Motor: 450 N Operating Range Y: 2...10 V Input Impedance: 100 kΩ Position Feedback U: 2...10 V Position Feedback U Note: Max. 1 mA Position Accuracy: ±5% Direction of Motion Motor: Selectable with switch Direction of Motion Note: Y = 0 V: switch 0 (extended) / 1 (retracted) Manual Override: With push-button, can be locked Stroke: 100 mm Running Time Motor: 150 s / 100 mm Sound Power Level: 52 dB(A) Safety and Certification Protection Class IEC/EN: III, Safety Extra-Low Voltage (SELV) Power Source UL: Class 2 Supply Degree of Protection IEC/EN: IP54 Degree of Protection NEMA/UL: NEMA 2 Enclosure UL: Enclosure Type 2 EMC: CE according to 2014/30/EU Certification IEC/EN: IEC/EN 60730-1 and IEC/EN 60730-2-14 UL Approval: cULus according to UL60730-1A, UL60730-2-14, and CAN/CSA E60730-1 Environmental Data Ambient Humidity Max.: 95% RH, non-condensing Ambient Temperature: -30...50°C [-22...122°F] Storage Temperature: -40...80°C [-40...176°F] Pollution Degree: 3 Rated Impulse Voltage Supply / Control: 0.8 kV Servicing: Maintenance-free Weight: 1.1 kg Operating Mode: The actuator operates with a standard control signal of 0...10 V, adjusting to the defined position. Measuring voltage U provides an electrical display of the damper position (0...100%) and serves as a control signal for other actuators. Simple Direct Mounting: Can be directly connected using the enclosed screws. The gear rod head attaches to the moving part of the application with the provided Z-KS1 coupling piece. Manual Override: Equipped with a push-button for manual control (the gear train disengages when the button is pressed or locked). High Functional Reliability: Overload protection ensures the actuator stops automatically when the end stop is reached, requiring no limit switches. Electrical Accessories: Positioner for wall mounting (SGA24) Positioner for built-in mounting (SGE24) Positioner for front-panel mounting (SGF24) Positioner for wall mounting (CRP24-B1) Mechanical Accessories: End stop kit, Multipack 20 pcs. (Z-AS1) Rotary support for linear actuator, for compensation of transverse forces (Z-DS1) Coupling piece M8 (Z-KS1) Installation Notes For optimal performance, authorised specialists should install the actuator following all applicable regulations. Ensure the device is protected from direct exposure to water, snow, ice, insolation, or aggressive gases. In applications with transverse forces, use the rotary support and/or coupling piece to avoid actuation force losses.
