Safety isolating transformers

More information

Transformers with basic insulation between primary and secondary windings designed to supply a SELV or PELV circuit (<50 VAC).

Safety isolating transformers are often used for low voltage installations in processing industry, switch boards, shipping installations, alarm equipment, automation, floor heaters and halogen lighting equipment.

Transformers without built in fuse arrangements must be protected against short circuit and overload with separate fuse arrangements. Information on losses and short-circuit values are found here:
