Single-phase separating transformers ET1S ** with the power between 0,05 and 2,5 kVA

Separating transformers are assigned for supplying lighting circuits, control, etc. In standard design, the transformers are adjusted to fastening by means of a base welded into core or screwed angles. 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. Upon request, the transformers may be assembled in enclosures with the protection degree of IP 23, IP 44 and IP 54 with the possibility to insert supply cables through glands.

*) - 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 400//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.
