N4L Power Analyzers cover 1 to 3 phase applications in one instrument
depending upon the model and up to 12 phases via N4L’s PPALoG software
application in both low and high current models. Each phase input has wide
ranging voltage and current channels which are fully isolated from each other
and from ground.
The voltage and current inputs are simultaneously sampled and the data is
analyzed in real time by a high speed DSP (digital signal processor). A separate
CPU (central processing unit) takes the DSP results for display and
communications. At the heart of the system is an FPGA (field programmable gate
array) that interfaces the various elements.
This powerful, versatile structure allows the measurement of a wide range of
power related parameters.

Care must be taken when connecting up the instrument.
Remember to configure the Voltage and Current inputs as per the diagrams
