Overview
The HA1600A is a fast, easy to use mains and harmonics analyser with a large and high resolution graphical display, capable of continuous real-time analysis.
The HA1600A is intended primarily as a dedicated harmonics and flicker analyser for compliance quality measurements, but it can also be used as a general purpose mains analyser.
The unit is available with range of power connectors to suit different national standards.
A printer interface is included for record keeping and archiving, along with both RS-232 and USB interfaces for PC connectivity.

High performance power analyser
The HA1600A is a high speed, high accuracy ac power analyser for single phase loads of up to 16 amps RMS.
Dual power cables allow the supply to the load to be independent of the supply to the instrument. The output to the load is via a front panel mounted ‘standard’ mains connector. A wide range of power connectors is available including most national types.
The HA1600A can measure Watts, VA, Volts rms, Volts peak, Amps rms, Amps peak, Crest factors, THD, Power factor, Frequency and Inrush current.
The large display can show multiple parameters simultaneously as well as graphical representations of voltage and current waveforms.
Dual 16 bit Analog to Digital converters continuously sample both voltage and current and give a wide dynamic range. A fast Digital Signal Processor gives the performance needed for continuous real-time analysis of the data. Advanced algorithms yield accurate results, using extended precision or floating point arithmetic wherever necessary.

Compliance-quality harmonics analyser
All electrical equipment sold within the EEC must comply with legislation relating to the harmonics content of the current waveform.
The HA1600A has been designed to make these measurements both quick and simple. It measures harmonics from the 1st to the 40th and updates the display in real time.
It is suitable for pre-compliance measurements using a normal mains supply and is capable of full compliance measurements to EN61000-3-2 in conjunction with a suitable power source such as the AC1000A.
Support is provided for both the 1995 and 2000 editions of EN61000-3-2. Capabilities include continuous monitoring of the supply voltage, continuous automatic calculation of harmonic limits, and timed test sequences with analysis of fluctuating harmonics.

Compliance-quality flicker meter
The HA1600A can operate as a compliance quality flicker and fluctuations meter in conformance with EN61000-3-3 and EN61000-4-15.
A current measurement method can be used, as an alternative to voltage measurement, thus eliminating the need for a reference impedance.
Flicker severity is measured in terms of Pst and Plt using analysis periods as defined within the standard.
Simultaneously full analysis of voltage variations is performed, including the calculation of the maximum value dmax, the difference between steady states dc, and the change characteristic d(t).
