6SE6420-2UD24-0BA1

The Siemens MICROMASTER 6SE6420-2UD24-0BA1 model is engineered as a robust variable frequency drive with impressive capabilities. Operating at a power rating of 4 kW, this device maintains efficiency at or above 97%, which supports cost-effective performance.

This drive operates within a three-phase input voltage range of 380 to 480 V AC, with an allowable tolerance of ±10%. The input frequency ranges from 47 to 63 Hz, helping it adapt to various electrical environments. The output voltage can vary from 0 up to the input voltage, providing flexible control over connected equipment.

The output frequency is adjustable from 0 to 650 Hz, coupled with a rated output current of 9.5 A. In scenarios where higher current demand occurs, the drive safely accommodates overload conditions, allowing up to 150% of its rated current for periods limited to 60 seconds. A linear V/f control methodology is employed to ensure precise motor control.

Users can customize the switching frequency, starting at 2 kHz by default, with the option to adjust it up to 16 kHz depending on the application requirements. The drive supports acceleration and deceleration ramps adjustable from 0 to 650 seconds, making it highly adaptable to various operational needs.

When it comes to braking capabilities, it can deliver up to 20% braking torque without a braking resistor and 100% with the addition of one. Unfortunately, the unit is rated IP20 in terms of protection, indicating it is designed for indoor use without significant exposure to water or dust. Operating temperatures range from -10°C to +50°C, permitting it to function in various settings while maintaining reliability.

In terms of dimensions, the drive measures 202 mm in height, 149 mm in width, and 172 mm in depth, allowing for simplified mounting and integration within control panels or enclosures.
