3810, 3410 series electronic electric actuator, is a 220V AC single-phase power supply as the driving power supply, accept 4-20mADC from the computer regulator or manipulator, or 1-5VDC input signal to operate the all-electronic actuator, there is a servo system in the machine, no need to be equipped with another servo amplifier, the key component "controller" adopts advanced hybrid integrated circuit, and is cast and cured with resin, aging treatment, high reliability, moisture-proof, shockproof. Use a potentiometer to adjust the zero point, stroke, sensitivity, which is convenient and easy; Use the function switch to arbitrarily select the three states of positive and reverse action, and select the broken signal. At the same time, the actuator has three protection functions: overload protection, temperature protection and compression spring to ensure the closing of the valve. It is a highly reliable product that can be combined with various linear and angular stroke regulating valves to form an electric control valve.
