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.
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.
