Approvals

UL 5085-1/-2, CSA 22.2 No.66

Applications

As a mains transformer for adjustment of the voltage and simple electrical isolation.
As an 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 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.
