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

CAD data

 
  • 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

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.
