7. Technical data
7.1 General specifications
• 4 galvanic isolated inputs for connection of U- and I-sensors
(either for AC, DC or ACDC), or
• for connection of one U-sensor (DC) and up to three
I-sensors (DCDCDC)
Ranges for rated input values
Rated voltage (secondary)
Rated current (secondary)
AC: 70 – 300 V or 17,9 – 100 mA
DC: 17,9 – 100 mA
AC: 50 – 2000 mA or 5A
DC: 50 – 2000 mA
Class 0,5 R (acc. to EN 50463-2) for ranges specified in the
line above.
In case of rated input values out these limits or for a multi-
system energy meter the class accuracy may be higher (0,75R
or 1,0R).
DC, 16,7 Hz, 50Hz and 60 Hz
