Precision Power Analyzer PPA5500 Overview

The PPA5500 Power Analyzer introduced leading power measurement performance in a compact, cost-effective instrument that quickly developed a reputation for exceptional accuracy and stability in the most demanding of power applications. The series extends the power analysis range further for those who need the ultimate power analysis product, this is the top-of-the-range model offered by N4L and rightly deserves its place. While maintaining the wide frequency range and exceptional noise rejection, the PPA5500 series adds increased voltage and current measurement ranges, greater processing power, increased memory, real-time clock, high contrast color display, 1GB non-volatile internal memory, and external USB memory port. A 2MS/s sample rate, alongside “True Real-Time” no gap analysis is a formidable combination for the analysis of power, this – along with innovative analog front end design which includes our proprietary “Planar shunt technology “, the PPA5500 provides truly exceptional measurement stability and accuracy. The phase angle accuracy of the PPA5500 is 0.005 degrees, this is perfect for transformer loss analysis testing at very low power factors. Have a look at the Power Analyzer Tutorial Series which demonstrated the speed and versatility of the PPA5500.
