The Siemens 6SE6420-2UD21-5AA0 is classified as an AC inverter and is part of the MICROMASTER series, specifically the 420 variant. This unit is engineered to work within a supply voltage range of 380 to 480 V AC, adjusting within a tolerance of ±10%. Operating within the input frequency scope of 47 to 63 Hz, the inverter boasts a power output rating of 1.5 kW, making it suitable for various industrial applications.

In scenarios requiring greater demand, this inverter can handle an overload of up to 150% for a timeframe of 60 seconds, enabling enhanced functionality for high-load situations. The maximum frequency supported by this model reaches 650 Hz, providing flexibility in motor control. The input current is approximately 5.9 A, while the output current is rated at 4 Amps.

Dimensions for the inverter are compact at 173 mm in height, 73 mm in width, and 149 mm in depth, making installation straightforward in locations with space constraints. This particular design has an IP20 protection level, signaling its suitability for dry indoor scenarios rather than exposure to direct water or dust.

This inverter operates efficiently across a temperature spectrum. It can function between -10°C and +50°C ambient conditions, ensuring versatility in various environmental settings. Mounting is facilitated through either DIN rail or bolt options, catering to different installation preferences. It is important to note that the device is unfiltered and relies primarily on V/f control for variable frequency drive operations. Adequate ventilation is required for effective thermal management during operation.
