SIPOS

In 1905, Siemens produced the world's first electric actuator, and SIPOS (SIEMENS Positioner) was a trademark of its electric actuator. SIPOS has been widely used in various industrial production fields around the world. Almost all of the actuators used on the bypass of all electric turbines in China's power plants are imported SIPOS. Siemens also sold its SIPOS1 series and SIPOS 3 series production technology to two manufacturing plants in China in 1987 and 1992, respectively.
