• For versions with increased climate-resistance,
the transformer is supplied with a
specially insulated finish. The finish
enables the transformer to be used in
areas of high humidity
• UL/CSA only up to 600 V (incl. tapping)
When ordering, the following information
must be added to the type designation:
ETSP25(*/*)
1st place holder ^= rated input voltage
2nd place holder ^= rated output voltage
Sample order
• required throughput rating: 55 kVA
• requested rated input voltage 400 V
• requested output voltage 230 V
Notes for selection
ST = SN · (1 - lower voltage )
= 55 kVA (1 - 230 V/400 V) = 23.4 kVA
ST = Type rated power = power, which is
relevant for the size of the transformer
SN = Throughput power = Nominal power,
which is the relevant figure of the load of
the transformer
• The type rated power is always smaller
than the throughput rating.
• Versions with delta stabilizing winding on
request.
The correct type designation reads
ETSP25(400/230)
The unambiguous article number of your
configuration will be defined by trafomodern
during the offer- and order process.
Higher outputs on request.
1) Rated output when used according to
insulation class B, maximum of 130° C in
the core; for insulation class F maximum
of 155° C in the core.
2) Excess charge for increased current
