CVMk2

4” ANSI Round Panel Mount Three Phase Kilowatt Hour / kW Demand Power Quality Analyzer

The CVMk2 power quality analyzer is highly accurate metering device which measures the main electrical parameters in three or four wire, single-phase and / or three-phase systems up to 600V.

Measurements are in true effective value (TRMS), using three voltage inputs and neutral (if available) with two or three external current transformers having a …/5A or …/1A secondary.

The CVMk2 analyzer records active, inductive reactive, capacitive reactive and apparent power per phase and system total. The CVM can also measure harmonics and neutral current, depending on model number. The entire CVMk2 has a built in power demand meter which calculates integrated demand in a preset period (1 – 60 minutes) using the sliding window method.

The CVMk2 can be supplied with additional functions from selected expansion cards. Optional cards include: analogue and / or digital outputs, which can be programmed to link with any measured parameter. Communications include: Modbus, Johnson N2, Profibus and Ethernet TCP/IP.

This meter can either be stand alone or “ganged” into a single enclosure for multiple metering applications.

The CVMk2 meter is a two piece unit including meter and LCD display. Up to 32 meters can be daisy chain connected to one LCD display, via CAT 5 cabling.

Connected to these meters are National Meter’s labeled +/- 0.5% - 1% accurate solid core, split core or bar type current transformers. Please consult NMI application engineer.
