Reactive power compensation in the floor-standing cabinet

Compensation system multicab-R-S

Reactive power compensation systems
multicab R 400 8 14 Gleit offen

The multicab-R-S compensation system provides you with high-quality, automatically controlled power factor correction in the floor-standing enclosure. With its standard dimensions, the floor-standing enclosure is compatible with any control room. If you require special dimensions, we are of course also flexible here.

Our standard are individually manufactured compensation systems that are explicitly designed for your specific application. This allows you to achieve reactive power compensation that is optimally tailored to your requirements. The convenient modular design also enables simple and flexible system expansion. All compensation systems are available choked to prevent resonance damage and thus extend the service life of the capacitors. Unchoked systems are also available.

KBR compensation systems are characterized above all by their quality and durability. We only use quality components in our handmade systems, most of which we develop and manufacture ourselves at our plant in Schwabach. The units have a temperature-controlled ventilation system that prevents damage to appliances due to overheating. In addition, the secureC safety and maintenance module and the automatic extinguishing system set new standards in terms of safety in compensation systems.
