Group A(C)

Group B(D)

4 independent power measuring channels,

extendable to 8 channels with extension box or second device

The current and voltage paths of the 4(8) power measuring channels are all
isolated to each other and to earth. This allows a high degree of measuring
freedom in many different power measurement applications.

Wiring settings in () are featured
by option „Star-Delta Conversion“

The adjacent table shows
various types of wiring for
grouped and individual meas-
urement channels. The table
also assigns application exam-
ples for the respective types of
wiring.
Power measurement channels
1(5) and 4(8) can each be
synchronised to their input sig-
nals (fundamental waves etc.)
independent of each other.
Channels 1(5) and 4(8) are then
the synchronisation references
for the other channels con-
tained in groups A(C)
and B(D).
This is a very useful method for
carrying out efficiency meas-
urements for equipment where
input and output have different
frequencies, for example a 3-
phase frequency inverter with
single-phase mains supply, or
uninterruptible power supplies
by use of 8 power measurement
channels.

Measuring accuracy

Accuracies based on:

1. sinusoidal voltage and current

4. definition of power range as the product of

2. ambient temperature 23 °C

current and voltage range, 0 ≤ IλI ≤ 1, (λ=Power factor=P/S)

3. warm up time 1h

5. calibration interval 12 month


Other values

All other values are derived from the current, voltage and active power values. Accuracies for derived values depend on the

functional relationship (e.g. S = I * U, ∆S/S = ∆I/I + ∆U/U)

Accuracy
