Siemens 6SE6420-2UD22-2BA1 Frequency Inverter

Siemens MICROMASTER 420 frequency inverter, model 6SE6420-2UD22-2BA1, is a three-phase variable-frequency drive designed to precisely control motor speed and torque in industrial equipment. Operating on a 3-phase 380–480 V input at 47–63 Hz, it delivers 480 V output with a rated power of 2.2 kW (3.0 hp) and a continuous output current of 5.9 A; the input current rating is 7.5 A. The drive supports an output frequency range of 0–650 Hz for V/f control, with a production-limited ceiling of 550 Hz, and offers overload capability of 150% for 60 seconds within a 300-second cycle. It is specified as IP20 with ambient operating temperature of -10 to +50 °C, and is available as an unfiltered variant for 380–480 V networks. The unit measures 202 x 149 x 172 mm (H x W x D). Suitable for applications requiring constant torque and variable torque motor control, MM420 drives are commonly used to regulate pumps, fans, conveyors, and machine tools in industrial automation environments. This model, 6SE6420-2UD22-2BA1, is part of Siemens’ MICROMASTER 420 family and is designed for robust performance in standard industrial control projects.
