Description
econ sens + is a compact, versatile energy consumption meter with a web interface and memory
function.
It measures the voltage and the current of the individual phases and the voltage between PE and the
neutral conductor.
When calculating the power, econ sens+ is able to differentiate between the generated and consumed
power. The energy consumption values calculated from the power data are displayed to the user via
the web interface and made available for any energy monitoring systems or similar that may be
connected via:
1. 2 x S0 pulse outputs to DIN EN 62053-31 (for consumed and generated active energy)
2. Modbus TCP
3. Modbus RTU (RS-485)
Allowed the detection of active, reactive and apparent power, current and voltage, each per line and
further readings on the Modbus interface (see Chapter Modbus).
The econ sens+ samples the input voltages and currents at 32 samples/signal period. To do this, it
tracks the frequency of the inputs and continuously updates its sampling rate accordingly. At the same
time, the econ sens+ resamples the input voltages at 1kHz. These samples give a picture of the
waveform. These waveforms are stored for several types of events.
The econ sens + has a size of 16MB memory to store values, logs and events. It holds power logs per
second for the last 2 days. It logs all measurements per minute for the last 39 days, per interval (10 or 15
