Safety isolating transformer
EL 7,5/18 - Discontinued types – not for new designs
Characteristics
General data
The safety transformers of the EL series provide safe galvanic isolation of the primary circuit from the secondary circuit and are manufactured according to EN (IEC) 61558-2-6. By limiting the output voltage, the transformers are suitable for the construction of SELV and PELV circuits.
Benefits
› Solder connection for free wiring
› With dual output coils for series and parallel connection
› Excellent corrosion protection and low noise emission thanks to BLOCK IMPEX vacuum impregnation
› Easy mounting with a sturdy metal base plate featuring elongated holes
