    Benchtop Power Analyzer up to 8 Phase Analysis | PPA3500

    High-Performance PPA3500 up to 8-Phases Power Analysis Overview

    The PPA3500 is a high accuracy 3~6 phase power analyzer able to perform reliable, accurate power analysis in a variety of applications. DUT to innovative analogue card design, the PPA3500 is packaged in a compact 2U chassis. The PPA3500 is available in 3, 4, 5 or 6-phase configurations. The PPA3500 power analyzer benefits from a full colour “Dual” TFT display, this concept employs two TFT displays within one instrument, allowing for a large widescreen display area in a 2U form factor. There is also the option to install the unit in a 19"| rack providing a 2U 6 Phase solution, see accessories for more details.

    Proprietary Technology featuring the industry-renowned planar shunt technology (A shunt design topology developed by N4L) and FPGA based real-time no-gap analysis techniques, the PPA3500 is able to provide groundbreaking 6-phase analysis performance. Real-Time no gap analysis ensures efficiency measurements are entirely synchronized between input and output.

    All PPA3500 units are supplied with UKAS ISO17025 certification as standard, this is performed at N4L in the UK in our accredited ISO17025 Laboratory.
