Overview
The AC1000 is an
innovative, low cost, pure power source designed specifically for use with
a harmonics analyser such as the TTi HA1600, permitting compliance quality
measurements to EN61000–3–2.
The AC supply available at a standard wall socket is usually distorted.
This comes about because of nonlinear loads (non–resistive loads) on the
AC supply such as transformers, fluorescent lights, switched–mode power
supplies etc. In a typical load there are rectifiers and capacitors that
cause current to be drawn from the supply only near the peak of the
waveform. The effect of this is to flatten off the top of the sine wave
causing significant distortion.
In a typical factory environment this distortion can be so significant
that it is easily visible using an oscilloscope.
EMC legislation (EN61000–3–2) has made mandatory the measurement of
harmonic current produced by electronic equipment, and requires that the
source supply provides a pure voltage waveform to the equipment under
test. The harmonic currents can differ significantly when a pure source is
used so it is important that any testing is performed with a device such
as the AC1000.
Compact and portable the AC 1000 is rated up to 1000 V·A for 230 V
operation and will supply 1000 V·A at 230 V input at up to 35°C
ambient. In contrast to other techniques which use a passive filtering
approach, the AC1000 uses an innovative technique which actively corrects
the AC supply to produce a harmonically pure output.

The AC1000 is also very useful for stress testing power supplies in
electronic equipment. The use of a harmonically pure, distortion free
device – such as the AC1000 – is essential to fully stress and
evaluate the power supply under test.
