EPA GmbH
About us
EPA GmbH was founded in 1988 as a sales company for frequency inverters. Due to the inseparable connection between electrical drive technology and EMC, the product portfolio was expanded in 1995 to include radio interference suppression components and the company began manufacturing EMC filters from its own development. In the meantime, EPA has become a well-known brand name when it comes to high-quality line filters and EMC products.
Driven by the steadily increasing component density of power electronics and the increased use of AC/DC sensitive residual current circuit breakers, the company has become the market leader in leakage current technology over the past 15 years through intensive research and development.
Planning, realization, commissioning, service, maintenance, formation of frequency inverters, production support and EMC measurements as well as devices for leakage current reduction/compensation plus individual consulting for customer-specific special solutions complete our product portfolio. This exceptional, cross-divisional competence in drives, EMC and leakage current technology makes EPA GmbH your partner in all matters.
