1.3 Overview of PQube 3 models and modules
PQube 3 Power Analyzer family
1.3.1 PQube 3
PQube 3 is the most popular model in the family. It is
easy to set up and comes from the factory with a default
set up so you can “plug and go” for most installations. It
auto-detects the mains frequency, wiring configuration
and nominal voltage. You can connect directly to up to
600 volts (nominal) and the device computes 4-
quadrant ANSI Class 0.2 revenue—grade energy on eight
single-phase channels and is certified for Class A power
quality according to IEC 61000-4-30 Ed3.
The PQube 3 holds years of data and thousands of
events via 32 GB of internal flash memory.
1.3.2 PQube 3e
PQube 3e is the natural extension of PQube 3 with 6
additional current channels, giving you the ability to
connect up to 14 energy metering channels.
The channels can be assigned in any combination of 4
three-phase loads or 14 single-phase loads. You can
quantify energy costs by monitoring multiple loads
with a single revenue-grade PQube 3e power analyzer.
