Characteristics

D000027979 en t – E350 Series 2, 3-Phase ZxF100Ax/Cx – User Manual
The meters have the following characteristics:

Recording of active and reactive energy in all 4 quadrants (ZMF100Cx)
or recording of active energy imported and exported (ZxF100Ax) with
up to 6 rates

Rate control performed via communication module

Data display on LCD

Measuring elements in DFS (Direct Field Sensor) technology with
excellent measuring characteristics, including flat load curve, high
stability and good protection against interference.

Active energy measurement accuracy: Classes 1 and 2 (IEC62053-21)
and MID accuracy classes A and B (EN50470-3)

Reactive energy measurement accuracy: Class 2 (IEC62053-23)

Correct measurement even with only one or two phases (for ZFF100
meters the correct measurement is only granted with missing phases
L1 or L3, since L2 is the internal reference point, which must always be
present)

Wide range measurement from starting current to maximum current

Serial interface with optical input/output for automatic readout of data
on the spot and for service functions

AMR interface (connection to communication module) for meter
reading and tariff control according to IEC 62056-21

Storage of event information (e.g. power outages)

Installation aids (e.g. phase voltages and direction of energy)
- Presence of phase voltages (voltage values are displayed)
- Visual output (no-load indicator) on LCD
- Display of energy direction
- Power indication
