Transformers Toroidal transformer RKD General Data Rated input voltage 2 x 115 Vac Rated output voltage 2 x 12 - 2 x 115 Vac Power 15 - 3000 VA Insulation class B Maximum ambient temperature 40 C Efficiency up to 98 % Degree of protection IP 00 Advantages Minimum size at high output Low weight Double input voltage for series or parallel connection Double output 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.
