Graphene Power Meter – GPM96
Power Quality & Energy Meter
Product Description
The GPM96 is part of the new smart
Graphene-Meter-Series. The unit measures
all-important system values like voltage,
frequency, power, power factor, THDV, THDI
harmonics (up to 63rd), displacement power
factor, voltage crest factor, current K-factor,
or voltage unbalance. The build-in Modbus
RTU (Optional TCP/IP) interface ensures
smooth communication to any other system.
Together with an accuracy class of Cl 0.5S
(IEC62053-22) makes the GPM96 an
allrounder and an ideal choice for any analysis
in all kinds of electrical systems.
