Single-phase safety isolating transformers with the power between 2,0 and 10 kVA


Safety isolating transformers are assigned for supplying electric devices with safe voltage. In standard design, the transformers are adjusted to fastening by means of 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. Standard enclosures have powder coating - colour RAL 7032.
