The POWER ANALYZER 3390 maximizes the advantages of both clamp-on current
sensors, which provide coverage up to and including the frequencies used by
inverters, and pass-through current sensors, which are capable of measurement at
accuracies approaching directly wired instruments. Leveraging our expertise in
clamp sensor engineering, proprietary HIOKI technology has made possible a
current sensor-driven power meter that delivers high accuracy throughout a broad
frequency range, making it well suited for motor evaluation.
Users can select from inexpensive clamp-on current sensors, which are available
in 20A to 500A AC as well as AC/DC types, to high-precision pass-through current
sensors, based on the requirements of their measurement objective.
Features:
Ideal for use in the development and evaluation of increasingly
efficient inverter motors
The 3390's new high-speed power analysis engine provides the motor
power efficiency and harmonic measurement functionality needed to
develop high-efficiency motors such as those used in hybrid automobiles.
Moreover, it delivers high-speed simultaneous measurement with a data
refresh rate of 50 ms (6 to 10 times faster than previous HIOKI models).
The newly developed high-speed power analysis engine eliminates the
need for a sampling clock, which was required by previous models to
measure harmonics at low motor speeds. The 3390 can perform automatic
measurement at the fastest refresh rate from 10 rpm to 100,000 rpm (with
a 6-pole motor).
Ideal for use in the development and evaluation of new energy
sources such as solar and wind power
The 3390 can simultaneously measure power conditioner input DC power
and output AC power while analyzing up to 100th-order harmonics and
measuring the distortion factor.
DC and True RMS current plus power integration functionality lets you
measure power drawn from and sold to the grid as well as power
consumption and regenerative power.
Ideal for use in inverter maintenance
Clamp-on current sensors make it easy to simultaneously measure
primary- and secondary-side power while analyzing up to 100th-order
harmonics and noise (FFT analysis).
Compact, lightweight design features an integrated handle for easy
portability.
