10kVA transformer
in IP34 enclosure

Transformers have been built to minimize load losses. The advantage with
ECO-transformer is low load losses,
low operating temperature and small
magnetic stray field. Also the inrush
current is lower than in POWERmodel. All this has been achieved
by decreasing the temperature rise
and magnetic flux density in the
transformer. All materials used are
of the highest quality from certified
suppliers. ECO-transformers have
lower operating costs than POWERtransformers.
