High force low noise linear actuator comes equipped with a built-in limit switch, 12-volt electric linear actuators use DC motor as the power source with a matching power controller. Power Controller Makes Electric actuator Running. The input voltage of the controller is generally 110V and the output voltage is 12V. It is very convenient to be used where there is power. The use of an electric actuator as an actuator not only reduces the air supply and auxiliary equipment required for pneumatic actuators but also reduces the weight of the machine. Compared with hydraulic cylinders, electric actuators do not require a hydraulic source and do not require complex system support, including pumps, pipes, valves, filters, and many joints. Therefore, from the perspective of energy saving, the electric actuators actuator has obvious energy-saving advantages over the pneumatic hydraulic actuator. https://www.hbactuator.com/low-n...ise-linear-actuator.html
