Single-phase isolating transformers ET1o ** with the power between 0,05 and 0,5 kVA for fastening on rail TS-35
Isolating transformers are assigned for supplying electric devices, if separation of electrical circuits required.
Special quick-to-fasten clamp enables the quick and easy mounting on the rail TS35 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//230 operating under normal conditions. For other conditions and data the values may change
Note:
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.
