Applications for EI - transformers

EI - transformers are spread the most. They are widely applicable because of the easy
fabrication of E and I sheets and an high amount of available bobbins

With incapsulated bobbins:

Medical technology: defibrillation devices, dental technology and for kidneymachines. We
are also able to build leakage current reduced transformers according to
EN 61558 VDE 0750.

Traffic technology: Railway technology, automotive engineering, aerospace, traffic lights
resp. transducers.

EI - transformers, mostly potted, are also suitable for lighting technology according to
EN 60598-2-6 VDE 0711 (luminaires with integrated transformers for incandescent lamps).

For the audio technology, e.g. transducers of 100V technology, EI - transformers are
proper. The windings are built up nested to achieve a better transmission of high
frequency. Furthermore you find EI - transformers as power transformers in boosters.

Solar technology inverter use EI - transformers as well. The mostly small output voltage is
transformed upwards. The air gap between E and I cause a throttling, which smoothes the
voltage peak.

For automation you find EI - transformers with higher power in open construction as well as
potted PCB transformers.

The metrology constitutes EI as electronic current provisioner for test systems.
EI - transformers redeem the laboratory apparatus norm DIN EN 61010 VDE 0411.

For making of domestic appliances and office equipment are EI - transformers prefered,
mainly because of the low prices when ordering high numbers. Norms like the domestic
appliances norm DIN IEC 65 VDE 0806 as well as the office equipment norm
IEC 380 VDE 0806 just as the norm for devices of the information technology
EN 60950 VDE 0805 are redeemed.

Welding euipment of any types e.g. ultrasonics-, synthetic- or metal welding equipment use
EI - transformers wth higher or lower power. The air gap caused of the sheet makes
EI - types temporary overloadable or saturable.

EI - transformers are also constituted in switchboards. Mounting angles which snap in rails
(e.g. TS 35) provide an easy and quick mounting.

They are also suitable for the supply of devices like textile machines or as
HV - transformers used in the paperindustry.

The applications for environmental technology as well as safety engineering, e.g. vacuum
potted, are up to date.
