TK SERIES

POLYLUX’S TK SERIES

Single phase UI isolating transformer (> 3150 VA)

The TK series is made up of single-phase isolation transformers with 230V input and 230V output that includes a rating range as from 3.15 kVA up to 50kVA.

This equipment is perfect for supplying continuous power to industrial, tertiary or residential installations or machinery.

Some of its utilities:

  • The isolation of circuits, being able to increase or decrease the voltage at the output.
  • 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 with a certain level of electrical noise, the use of a transformer helps to improve the quality of the electrical network in its secondary.

We can find different versions depending on their degree of protection:

  • TKX: IP00
  • TKW: IP23
  • TKZ: IP54/65

Constructive features:

  • All the transformers are dipped in anti-flash varnish and then compacted in the oven. This process increases the insulation grade, reduces noise and provides anti-moisture, waterproof protection.
  • All the connection terminals are made of copper. For transformers with aluminium coils, internal bimetallic AL-CU connections are made by welding with filling and sealing material to ensure a safe, long-lasting connection.
