Key benefits

Configure the ideal solution

Combine modules freely to meet precise application needs, adapt quickly and scale easily. Preconfigured transport units reduce installation time, while the modular design enables smooth integration into any plant or system.

Reduce operational costs

Use efficient air or liquid-cooled modules to lower energy consumption and minimize CO₂ emissions. Easy-to-access components and shared DC link energy exchange simplify maintenance and help lower overall lifecycle costs.

Depend on long-term reliability

Rely on robust construction and proven mechanical stability designed for harsh environments. Thorough testing and integrated EMC measures provide consistent performance and deliver a durable, highly available drive system.

Featured capabilities

Standardized interfaces and smart engineering

Uniform connection points enable fast and consistent engineering. Modules integrate seamlessly with the SIZER engineering tool for simple selection and planning. Comprehensive documentation supports the entire lifecycle.

Versatile air- and liquid-cooled modules

Powerful air-cooled units up to 4560 kW and liquid-cooled units up to 5700 kW deliver high power density, excellent adaptability and strong efficiency — ideal for applications exposed to demanding industrial environments.

Compact active line and motor modules

New liquid-cooled compact modules reduce installation footprint and provide flexible, space-saving solutions for main and auxiliary drives. Their robust design supports use in marine, offshore and other restricted environments.
