TTH SERIES

POLYLUX’S TTH SERIES

Three phase transformers for electrical medical installations.

Our TTH series is made up of three-phase isolation transformers with 400V input voltage and 230V output voltage and with rating range as from 1000VA up to 10000VA.

They are designed for use in medical electrical installations, being manufactured in accordance with the IEC/EN 61558-2-15 standard focused on safety in installations in clinical installations, guaranteeing patient safety.

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

  • TTH: IP20 cast resin
  • TTHX: IP00
  • TTHW: Inside IP23 enclosure
