ETSP, ETFSP – Single-phase autotransformers


Designed and tested according

· IEC/EN 61558-2-13/EN 60076-1

Typical applications

· Cost-efficient solutions for voltage adjustment

Basic equipment

· Insulation class B / F ab 6,3 kVA
· Ambient temperature –25 to 40 °C
· Connection terminal (<=115 A) · Frequency 50/60 Hz

Other available accessories

· Protective enclosure IP23
· Additional tapping
· Conductive screen
· Temperature monitoringg
· conductive screen
· Tropic-proof equipment

Sample order

· required throughout rating: 55 kVA
· requested rated input voltage 400 V
· requested rated output voltage 230 V

Notes for selection
· SN = S x (1 – lower voltage / higher voltage) =
55 kVA (1 – 230V/400V = 23,4 kVA
· ST = Type rated power = power, which is relevant for the size of the transformer
· SN = Throughtput power, Naminal power, which is the relevant figure of the load of the transformer

The type rated power is always smaller than the throughtput rating.

Versions with delta stabilizing winding on request.

The correct type designation reads ETFSP25(400/230). The unambiguous article number of your configuration will be defined by trafomodern during the offer- and order process.

Higher outputs on request.

Technical notes

Important notes:

  • For versions with increased climate-resistance, he transformer is supplied with a specially insulated finish. The finish enables the transformer to be used in areas of higher humidity.
  • UL/CSA only up to 600 V (incl. tapping)
  • CUR according to EIS130 or EIS 155 to OBJY2. or OBJY8.E160829 (Systems, Electrical Insulation – Component bzw. Systems, Electrical Insulation Certified for Canada – Component)

When ordering, the following information must be added to the type designation:

  • ETFSP25(*/*)
  • 1st place holder ≙ rated input voltage
  • 2nd place holder ≙ rated output voltage
