Motor soft starter SAE

semiconductorelectronicsingle-phase

Simple switching processes, in which a ramp-up time is required, are be carried out using efficient soft starters. The SAE is a single-phase controlled soft-starting device designed under the protection class IP20 to be attached to a 35 mm standard rail in the control cabinet. Thanks to the terminal configuration suitable for switchgears, as well as the compact design the SAE fits into any type of control cabinet and is also suited for retrofit systems. The ramp-up time and the motor's initial torque can be adjusted separately. The adjustable potentiometers are located behind the removable front cover. If the maximum current becomes effective after the adjustable acceleration ramp has elapsed, a relay contact will bridge the power semiconductor, so that the motor will be entirely driven by the main power supply.
