Applications

  • TK transformers are used for the galvanic isolation of single-phase installations in the industrial and tertiary sectors for safety reasons.
  • They are also used in the generation of ground referenced neutrals in high rating single-phase installations.
  • On the other hand, in installations where there may be several earth leakages, TK transformers ensure supply by preventing the tripping of the main differential circuit breaker.
  • To change the neutral regime of the installations, being able to go from a two-phase network to a single-phase network or vice versa (this case implies the generation of the artificial neutral).
  • In installations where there may be small voltage peaks or with a certain level of electrical noise, the use of a transformer helps to improve the quality of the electrical network in its secondary.
  • In outdoor installations where weather conditions are adverse, the TKZ version with IP-54 external enclosure offers an optimal solution.

Available accessories

  • PTC probe.
  • Bimetallic probe.
  • Temperature control unit
