drive electronics SK 500E - Modular frequency inverter

Product Description:

SK 500E - Modular frequency inverter

Following its introduction in the market the SK 500E product series has become successfully established and now the power range has been extended to 90kW. This extends the success factors of these components to a wider field of applications.

Modular compact inverter: SK 500E

With the SK 500E series of frequency inverters, Getriebebau NORD offers intelligent and costeffective drive solutions with scaleable equipment options, which are all fully compatible with regard to motor performance range, supply voltage and sizes. The basis for all models is a well-equipped basic unit with expansion possibilities through optional modules. SK 500E inverters are suitable for all application areas and can be easily adapted to specific requirements with plug-in technology units.

Performance grading:

The SK 500E product series offers a wide range of features which are necessary for application-specific drive solutions. Through different configuration levels, these can be used "in the same box". The inverters include the following functions, which are state-of-the-art for industrial applications.
