About ELFIS

ELFIS spol. s r.o. develops, manufactures and services industrial electronics, mainly EMC interference filters, sinusoidal filters, reactors, power regulators, chargers and inverters. It also resells UPS systems, frequency converters, flow and level meters, and provides UPS service, including installation, preventive checks, repairs and battery replacement.

The website describes its customers as industrial and business users of power electronics and UPS equipment, and the company sells both its own products and purchased goods, with after-sales service. The company was founded in 1991 as a limited liability company, with its office and production site at Kolmá 10 in Prague 9, where it has been based since 1996. The site lists certification as a service centre for EATON/POWERWARE, BORRI, ADPOS and LEGRAND brands, and ISO 9001:2015 quality management.

The website shows a contact address in Prague 9 and a phone number and e-mail, and mentions open positions in its menu, but the page content does not specify hiring details. The product range includes GPU and PCA ground power units for aircraft and custom application development.

Product: Own-brand EMC filters, reactors, power regulators and inverters, plus UPS sales and service for industrial customers.
