The ACl000 is an innovative, low cost, pure power source designed specifically for use with a harmonics analyser such as the Laplace AC2000, 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 the distortion 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 vary 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 AC1000 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 ACl000 is also very useful for stress testing power supplies in electronic equipment. The use of a harmonically pure, distortion free device - such as the ACl000 - is essential to fully stress and evaluate the power supply under test.
Specification Input voltage: Factory set to 230V/50Hz, 230V/60Hz, 110V/50Hz or 110V/60Hz Supply Tolerances: 230V setting: 198V - 253V
110V setting: 90V -127V
50Hz setting: ± 0.5Hz
60Hz setting: ± 0.6HzOutput Voltage: Tracks the amplitude of the fundamental of the input voltage. A variable voltage input may be used to adjust the output voltage to within the limits specified by EN61000-3-2. Output Distortion: Dependent on the purity of the input but will generally meet the requirements of EN61000-3-2. Output Current: Maximum continuous output current is 4.4A. Output Power: Maximum output power is input voltage x 4.4 VA Input Connection: Maximum output power is input voltage x 4.4 VA Output Connection: U.K., Schuko, or other national outlet sockets. Load power switch can be set to direct or corrected for ‘A—B’ comparisons. Protection: Thermal trip automatically diverts load to a ‘direct’ connection in the event of thermal overload. Operating Range: 5°C to 35°C at full rated output. Storage Range: -40°C to +70°C Environmental: Indoor use at altitudes to 2000m, Pollution Degree 2. Safety: Complies with EN61010-1 EMC: Complies with EN61326-1 Size: 307 x 105 x 225 mm (W x H x D) Weight: 5 kgs. View Adobe PDF File
