The Siemens part number 6SE6430-2UD31-5CA0 belongs to the MICROMASTER series and functions as an AC drive inverter designed for industrial applications. This unit is rated at 15 kW (20 horsepower) and accepts three-phase AC input voltages of 380 to 480 V, within a tolerance of ±10%. Operating effectively in a mains frequency range of 47 to 63 Hz, it suits various applications.

The output voltage produced by the inverter directly correlates with the input supply, maintaining a consistent three-phase voltage output. Frequency outputs are adjustable from 0 Hz to 650 Hz, although production limits peg the maximum frequency at 550 Hz for consistency in performance. The unit’s overload capability allows it to withstand peaks of 140% for 3 seconds and 110% for up to 57 seconds when operating within a 300-second cycle.

For efficiency, this model includes an energy efficiency rating of 0.96 with a power factor of 0.95, making it suitable for energy-sensitive applications. The cooling system utilizes forced-air cooling via an integrated fan, which enhances thermal management during operation.

Housed in an IP20-rated enclosure (UL open type), the unit measures 245 mm in height, 185 mm in width, and 195 mm in depth, with a total mass of 5.70 kg. This design allows for flexible mounting options within various industrial environments.
