Linear Electric Actuators L-250

Description: Thrust: 250 kgf/550 lbf Weight: 9.5 kg/21 lb Motor: 15 W Mounting Flange（ISO 5210）: F07 Max. Stroke: 50 mm/1.969 inch Feature: Enclosure: IP67、NEMA 4X：Water-proof and dust-proof enclosure. Material：Dry powder coating aluminum alloy. Position Indicator : All models are equipped with continuous mechanical position indicator. The external stem visual position indicator provides easily read and instantly available stem position. Modulating Controller : Actuator can be operated according to input signal and provide the output signal for feedback. Input signal：4-20mA, 1-5V or 2-10V. Output signal：4-20mA or 2-10V. Adjustable Stroke : Allow users to adjust actuator’s stroke to match valve stem’s stroke. (Refer to the specifications for stroke range) Motor : All models are equipped with DC motor and provide low power consumption, high duty cycle and efficiency.(1500 starts per hour) Working Conditions : Ambient temperature：-30℃ to +65℃ / -22℉ to +149℉ The humidity：30％ to 95％ Over-thrust Protection : If the output thrust of the drive exceeds of the drive rating, the actuator will shut off by two-step control. The two-step control is as follows: First step : If the output thrust of the drive exceeds the rating, power supply will be turned off by limit switches. Second step : If the limit switches fail, power supply will be turned off by electronic detector. (The function only applies to modulating controller actuator) Slow-speed operation : Besides the standard operating speed, if slower operating speed is needed, please contact with our sales person. Conduit entrance : standard : 1/2” NPT option : M20 or 3/4” NPT Various voltage : 24V AC/DC 110/220V AC
