Toroidal safety isolating and isolating
transformer
RTE
General Data
Rated input voltage 230 Vac
Rated output voltage 2 x 12 - 2 x 35 Vac
Power 15 - 625 VA
Insulation class B
Maximum ambient temperature 40 °C
Efficiency up to 95 %
Degree of protection IP 00
Advantages
Minimum size at high output
Low weight
Double output voltage for series or parallel connection
Protected against overload by integral temperature fuse
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 as specified in EN 61558-2-6 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 as specified in EN 61558-2-6 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.
