TTi AC1000A - USA Power Source Low Distortion 1kW

Optional Low Distortion 1kW Power Source

The AC1000A USA is a low cost pure power source designed specifically for use with a harmonics analyser such as the HA1600A.

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.

EN61000–3–2 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 for true  compliance measurements it is important that any testing is performed with a device such as the AC1000A.

Because of the large increase in the peak currents that can result from having a pure sinewave maims  voltage supply, the AC1000A is also very useful for stress testing a wide variety of power supplies types within electronic equipment.

Compact  and  portable, the  AC1000A  is rated at 1000 V·A for 230 V operation at up to 35°C ambient.

Maximum continuous RMS current is 4.4A with a peak current capability of 10A.
