In addition to the standard products for industry, several products for the automotive sector are also available. Applications such as on-board chargers in the 3.3 kW or 6.6 kW power class are the focus of Elec & Eltek here. But a CMC solution for 22 kW is also available. Please contact our team for details, since a customized solution is often necessary in this area.
EEMPL was established in 1993, initially producing power magnetic transformers. After an extensive development period, EEMPL expanded its product line to include data magnetics. Today, EEMPL manufactures a large and comprehensive range of high quality magnetic components, which includes connectors with integrated transformers, data and telecom transformers, magnetic power products, noise filters etc.
EEMPL products are widely specified for use in applications including Networks (LAN/WAN), Telecommunications, Broadband Access, Automotive and other industrial areas
Our team will be happy to advise you on components for power supplies. In addition to the common mode chokes from EEMPL presented here, we also offer power semiconductors such as protection diodes (Si or SiC), bridge rectifiers or MOSFETs from Bruckewell.
