Single-phase separating transformers 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.
