Single-phase power transformers ET1S ** with the power between 2,0 and 100 kVA

Power transformers are assigned for supplying electric devices, and for application in various industrial branches. 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/E2 (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//400 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.
