Measurements

Single phase and three-phase 3-wire or 4-wire unbalanced load operation.
True RMS metering provides accurate measurement even for distorted waveform.
More than 35 electrical parameters are measured. The basic version displays on the LCD the system values for a quick and easy check of the load conditions. The table on the right shows the measured parameters and the available options.
Programmable 1A / 5A current full scale allows to fit the standard CTs.
CT primary value is programmable up to 9999 to show the real energy consumption values

Front panel display

High contrast LCD display.
Two keys ensure the selection of the information on the LCD display and the instrument programming.
Password protected setup and resetting operations.

Communication

RS485 optoisolated communication port (option).
Selectable MODBUS or A2 ASCII protocol. LONBUS protocol on request.
Communication speed programmable up to 57600 bps (78 kbps in case of LONBUS).

Inputs & outputs

Two digital optoisolated outputs for energy pulsing. The pulse value is programmable.
On request input for Rogowski coils.

Advanced diagnostic functions

Wrong current transformer polarity and phase sequence connection errors are indicated on the LCD display.
Over / undervoltage, overcurrent and frequency out of range are detected to indicate the uncorrect working conditions.
Pulse emission frequency too high or CT too high are checked to indicate programming mistakes.

(1) The basic instrument is powered from L1, L2, L3 and N (4-wire version) or L1, L2, L3 (3-wire version). The presence of only one of the three phases (4-wire version) or two phases (3-wire version) ensures the normal counting and displaying operations.
(2) The serial port is powered from L1 and N (4-wire version) or L1 and L2 (3-wire version). The communication function is ensured only if the L1 phase (or L1 and L2 for 3-wire) is present and within the specified range.
