Datasheet

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.
