Block ACT25 Catalog Page

Safety isolating transformer

ACT 25

Advantages

Integrated short-circuit and overload protection thanks to temperature fuse
in the input and fuse in the output (ACT 10 only temperature fuse)

Permanent corrosion protection, high insulation value and maximum
electrical reliability thanks to XtraDenseFill resin encapsulation

Robust plastic housing for rail mounting, e.g. in consumer units or meter
mounting boards

Applications

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.
