Isolating transformer for the safe electrical isolation of the input and output
sides. The transformer may be used to set up protective separation as a
protective measure in accordance with VDE 0100.
As a control transformer for the electrical isolation of the input and output
sides.The construction of the transformer to supply control systems according
to VDE 0113 is designed.
As a safety isolating transformer for the safe electrical isolation of the input
and output sides. The transformer is suitable for creating SELV and PELV
circuits because of the limit on the output voltage.
