1
Data for 3-phase systems are valid under symm. conditions (0 °, 120 °, 240 °).
2
For higher current or output power demands connection of an external amplifier is possible (e.g.,
CMA current amplifier). The power data refers to an output current of 12.5 A
eff
or 12.5 A
DC
.
3
Single-phase model (operation with two phases in phase opposition):
two currents in series, additional adapter SPA1 or SPA156 recommended.
4
3 phases (3 x 9 A) in parallel for in-phase operation.
5
rd. = reading; rg. = range, whereat n % of rg. means: n % of upper range value (12.5 A).
6
Values at 50/60 Hz, 20 kHz measuring band width, nominal value and nominal load.
