DC electrical meter

Power meter and two-way DC energy meter for 8 users.
It detects the current directly from 8 Hall effect sensors with full scale - / + 25A; it measures the voltage from 30 to 60Vdc.

For each user enabled: calculates the instantaneous power, calculates the energy and stores the respective consumption in retentive counters with circular buffer.
DEM8H16 also acquires the open circuit-breaker status of each user even with zero current, detects the ambient temperature from the NTC10K sensor (option).
DEM8H16 is equipped with a power good SPDT relay to signal faults and / or to signal the diagnostic of the anomalous status of "open programmed switch closed".
All measured, calculated and acquired values are available via RS-485 multi-point serial interface with Modbus® rtu protocol.
It is equipped with an RS-232 "service" serial port which allows the complete configuration of the instrument from P.C. through the Dem8H16 program which also allows the monitoring of the variables and the reset of the energy meters of each single user.
