Description
The Siemens MICROMASTER 420 is a versatile and compact frequency inverter designed for controlling the speed of three-phase AC motors in industrial automation applications. This listing includes two models: the 6SE6420-2UD22-2BA1 (2.2 kW) and the 6SE6420-2UD27-5CA1 (7.5 kW). Both units operate on a 380-480 V, 3-phase AC supply and are supplied without a built-in EMC filter, offering flexibility for installations where external filtering is preferred or already in place. Featuring advanced V/f control and flux current control (FCC), these inverters provide precise motor control for applications ranging from pumps and fans to conveyors and mixers. The modular design allows for easy integration into existing control systems.
