 S-Engineering manufactured three group frequency converters based on the Siemens Sinamics S120 solution with a general power of 5.1 MW, which consist of 46 cabinets.

The uniqueness of the project consists in a non-standard solution of cabinets, which was created by S-Engineering designers with a maximum DC bus system current of 5900A. Due to the high power, the equipment requires intensive cooling, therefore, the height of the cabinets together with the ventilation compartment is 2800 mm, which ensures sufficient air exchange for forced cooling of the inverters.

Frequency converters have a degree of protection IP43.

Modular frequency converters are designed to control the rolling tables of the hot rolling mill of steel rolling production.
