    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.

  • Programmable Power Sources AC+DC 3kVA ~ 67kVA

    Programmable Power Sources AC+DC 3kVA ~ 67kVA | N4A

    Programmable Power Sources - Overview

    The N4A range of Programmable AC Power Sources offers complete flexibility for a wide range of applications. All N4A sources feature dual-channel arbitrary waveform generators utilising direct digital synthesis, providing the user with simultaneous multiple harmonic generations, frequency sweeping, and long sequencing capabilities. The metrology of the arbitrary generator permits long custom waveform sequences to be produced without a reduction in the resolution of each waveform. The N4A AC Source also features a 10-bit vertical resolution and a maximum waveform resolution of 16,384 points to produce a single periodic waveform. There is also an internal storage function for imported custom waveforms featuring user-intuitive library menus that display the waveform graphically on the display.

    The N4A AC power sources feature an extremely flexible waveform generator capable of mathematical waveform generation, data point waveform upload, and many sequencing functions. Traditionally, switching topologies have struggled to provide total harmonic distortion (THD) figures below 2%. The N4A “6-legged topology” provides less than 0.3% THD and typically 0.1%, the N4A range of AC Power Sources should be considered the best value power generator on the market. Ranging from the N4A06 6kVA model (300Vrms, 20A) to the N4A67 67kVA model (67kVA, 75A /phase) – the N4A will suit a wide range of applications including;
