Safety isolating transformer

RKD 300/2x12

Advantages

Minimum size at high power

Low weight

Dual input voltage for series or parallel connection

Minimal no-load losses

Outstanding temperature behaviour thanks to low magnetic leakage field

Very low noise field

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.
