Single-phase safety isolating transformers with the power between 0,05 and 0,5 kVA for fastening on rail TS-35

Safety isolating transformers are assigned for supplying electric devices with safe voltage.
Special quick-to-fasten clamp enables the quick and easy mounting on the rail according to EN 50022. If agreed, the transformers may have more tappings. The windings terminals may be placed on one side only, or on both sides of a transformer.

*) - for transformer design with climatic/environmental class C2/E1 (maritime design W/3 or tropical design T/3) the letter "M" or "G" ought to be added depending on final application
**) - this table was prepared basing on the technical specification for transformer with voltage ratio 230//24 operating under normal conditions. For other conditions and data the values may change


Manufacturer reserves the right to make changes resulting from the continuous development of products offered.

If requested in advance, it is possible to manufacture transformer in other version.
