Designed and tested according

  • IEC/EN 61558-2-1 / EN 60076-11

Typical applications

  • Voltage adjustment

Basic equipment

  • Insulation class B / F from 6,3 kVA
  • Ambient temperature –25 to 40 °C
  • Connection terminal (<=115 A)
  • Frequency 50/60 Hz
  • Vector group Yna0
  • Maximum load to neutral point: 10% of nominal current

CAD data

 
  • For versions with increased climate resistance, the transformer is supplied with a specially insulated finish. The finish allows the transformer to be used in areas of high humidity.
  • CUR according to EIS 130 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:

DTSP10(*/*)
1st place holder ≙ rated input voltage
2nd place holder ≙ rated output voltage

Sample order

  • required throughput rating 22 kVA
  • required rated input voltage 690 V
  • required output voltage 400 V

Notes for selection
ST = SN x (1 - Lowervoltage / Highervoltage) = 22 kVA (1 - 400V/690 V) = 9,25 kVA
ST = type power = power, which is relevant for the size of the transformers
SN = nominal power = power, which is the relevant figure of the load of the transformers

  • The type rated power is always smaller than the throughtput rating.
  • Versions with delta stabilizing winding on request.

The correct type designation reads DTSP10,0(690/400)

The unambiguous article number of your configuration will be defined by trafomodern during the offer- and order process.
