The RM 4100 Series is a replacement to the present
day Energy Meters (3 ph /4 wire). It displays Instantaneous
Power (kW) as well as the Cumulative Energy (kWh) consumption
of the connected load. In addition the meter also displays
Current Date and Current Time. The meter is based on
state of the art micro controller based technology &
measures true RMS values. The meter is suitable for
HT as well as LT side & has selectable CT/PT ratios
via the software
The meter is Special in the sense that it is provided
with an RS 485 port which enables its connectivity into
a network as well as to the PC.
