The HA1600A from Thurlby Thandar Instruments (TTI) is a Harmonics and Flicker Analyzer with a frequency range from 43 to 67 Hz. It complies to the EN61000-3-2 standard for harmonics analysis and the EN61000-3-3 standard for flicker measurement. This analzyer is primarily designed as a dedicated harmonics and flicker analyser for compliance quality measurements and can also be used as a general-purpose mains analyzer. It can measure power, voltage, current, phase angle, etc. for single-phase loads of up to 16 A (RMS). The analyzer uses dual power cables that allow the supply to the load to be independent of the supply to the instrument. It employs dual 16-bit Analog to Digital converters that continuously sample both voltage and current and give a wide dynamic range.

The HA1600A features a fast digital signal processor gives the performance needed for continuous real-time analysis of the data and utilizes advanced algorithms yield accurate results, using extended precision or floating-point arithmetic wherever necessary. It has a large and high-resolution graphical display, capable of continuous real-time analysis. The analyzer comes with the HA-PC Link Plus software (Windows-based) to assist users in taking routine compliance measurements and archiving the results. This harmonics and flicker analyzer includes a printer interface for record keeping and archiving, along with both RS-232 and USB interfaces for PC connectivity. It offers a comprehensive tabular display showcasing all parameters, including the latest and highest inrush current. The analyzer provides a waveform graph display for voltage and current, featuring normal, max hold, accumulate, and multiple cycle options for a detailed and dynamic analysis of electrical characteristics.

The HA1600A is available in an enclosure that measures 357 x 132 x 235 mm and requires an AC supply of 115 V/230 V.
