Single-phase isolation transformers with low inrush (<=5In)

Single-phase isolation transformers with low inrush (<=5In)

Advantages

Dry type transformer.

Efficiency higher than 95%.

Low losses, reducing the consumption of the installation.

Low noise < 40Db

Low connection peak between 3 and 5In, for B or C curve input protection and at its rated current.

Maximum overload 200% 2 seconds.

Finished in anti-flash varnish, by immersion offering:

  • Protection against corrosive environments.
  • Increased electrical insulation.
  • High compacting power.
  • Reduction of the noise level.
  • Increased product life.

Safety class I.

IP-23 enclosure, metal enclosure painted with polyester resin RAL 7035 (cat. C3 ISO 12994-2).

Possibility of customized manufacture if different specifications than standard are suitable.

Applications

  • TK5IN transformers are used when galvanic isolation is required in single-phase installations.
  • They can be used to switch from Phase-Phase to Phase-Neutral.
  • To disconnect the neutral from earth in those installations with grounded Phase-Neutral.
  • In installations where we have loads that in normal operation have a high level of earth leakage, the TK5IN transformers can isolate them, thus avoiding the untimely jump of the differential.
  • In installations where there may be small voltage peaks or electrical noise, TK5IN transformers help to improve the quality of the signal that feeds the loads.
  • In outdoor installations where weather conditions are adverse, the TK5INZ version with IP-54/65 outdoor use offers an optimum solution.

Available accessories

  • PT100 sensors.
  • Bimetal sensors.
  • PTC sensors.
  • Temperatura control unit.
  • Metal enclosure painted with polyester resin RAL 7035 (cat. C5 ISO 12994-2).
