RKD 20/2x24-1

Advantages Minimum size at high power Low weight Dual input and dual output voltage for series or parallel connection Minimal no-load losses Outstanding temperature behavior due 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. Sample application Mains transformer to: VDE 0570 Teil 2-1, DIN EN 61558-2-1, EN 61558-2-1, IEC 61558-2-1, UL 5085-1/-2, CSA 22.2 No.66
