OUR PASSION

GridClass® Mod
GridClass®Mod is a product range consisting of innovative, modular filter and compensation systems that enable a broadband filter effect across the entire frequency spectrum, resulting in a significant improvement in the voltage quality of the customer’s network. Broadband interference sources require broadband filtering measures in order to achieve an optimized power quality result. Switchgear builders in particular benefit from our modularly expandable and different filter technologies SOFIA®mod, RESI mod, MiA®, SIMΩN® and CLASSIC mod to provide their customers with the perfect filter solution.
Advantages
- Switchgear manufacturers only pass on their own company name to their customers.
- The performance and value creation of filter integration remains with the switchgear manufacturer
- GridClass® Mod are modular power quality solutions that can be expanded as needed at any time
