Safety isolating transformer
EL 7,5/12
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
