    High-Performance Power Analyzer PPA4500 Overview

    The PPA4500 features high-speed FPGA/DSP sampling techniques and the highly respected “Planar Shunt” Technology. The PPA4500 is the product of over 12 years of research and development. The PPA4500 has improved accuracy, color TFT, front USB port, and faster processing than older models. The PPA4500 is a significant leap forward in both accuracy and functionality. The PPA4500 is suitable for transformer loss testing, PWM inverter drive efficiency testing, standby power testing to IEC62301/EN50564, and many more challenging applications.

    The PPA4500 can measure fundamental frequencies up to 2MHz, as well as up to 100 Harmonics with the same 2MHz upper-frequency limit. PWM Motor drive mode enables the engineer to rapidly set up the instrument to measure complex harmonically distorted waveforms, sophisticated signal processing algorithms facilitate high sample rate (2Ms/s) true wideband (2Mhz) analysis of PWM signals. The PPA4500 utilizes parallel digital filtering for fundamental frequency synchronisation without affecting the bandwidth of the measured data.

    Power Analyser PPA1500 - Overview

    The PPA1500 Power Analyser offers higher performance compared to its sibling – the PPA500 unit.  N4L power analysers provide optimum solutions in almost any power measurement application and budget. The PPA1500 offers a 1Mhz Bandwidth and full graphic display, this includes harmonic bar graphs and graphic data logging. It features sophisticated parallel digital filtering algorithms enabling the PPA1500 to be used in various Pulse Width Modulated applications.

    While being only half-rack width and 2U high, the PPA1500 is available in 1, 2 or 3-phase configurations and offers a level of performance normally found only in larger and more costly instruments. With modes such as “Inrush Current and “Standby Power”, the PPA1500 provides fast, accurate and easy measurements in challenging environments.

    The PPA1500 series analysers now have a 6 Phase 2U Rack option in which two PPA1530 units are installed on the same rack side by side to give the ability to perform 6 Phase 0.1% accurate power measurement whilst only occupying a height of 2U in any rack.

    All PPA1500 units are supplied with UKAS ISO17025 certification as standard, this is performed at N4L in the UK in our accredited ISO17025 Laboratory.
