The AN61 series AC Power Supply adopts advanced SPWM technology, DSP digital processing technology and high-power switching power supply technology, in the field of AC power supply, it is leading in China and advanced internationally, and thus widely applied for the labs and production lines in power electronics, avionics, IEC standard test and other industries. AN61 series product possesses excellent power output quality: AC voltage output accuracy 0.4%; degree of distortion less than 0.3%; load effect less than 0.5%; can output AC, DC, AC+DC power and provide AC load, DC load and rectification load with precise power input. It has the ability of offering 6 times peak current and is optimal test instrument of measuring the surge current, and can be used to set the angle of waveform switch for testing the surge current and output holdup time. It can also be used to set the fluctuation ratio of voltage and frequency for scanning the range of power input to be tested. AN61 series product can simulate abnormal instantaneous rise, instantaneous drop, short circuit, jitter and others of electric supply, with the superposition function of harmonic waves or indirect harmonic waves, simulate the waveform distortion of electric supply, can also provide accurate and quick measurement of power parameters and harmonic waves, such as voltage root-mean-square value(Vrms), current root-mean-square value (Irms), true power, frequency (Hz), power factor (PF), current peak factor (CF) and 40-order current spectrum component. AN61 series AC Power Supply possesses strong programmable function, can complete the immunity test of IEC61000-4-1(test before certification) /-4-13/-4-14/-4-28 standard. Also, its programmable output impedance, together with the power analyzer, can complete the test of IEC61000-3-2/-3-3 harmonic wave current limit and flicker and is optimal choice of IEC standard test. Application: 1.Simulate power supply input interference Pulse, ladder, sequence and other output modes, simulating of any output wave in one step or continuously to simulate grid fluctuation 2.Testing of switching power supply inrush current Free setting of start/stop angles through the output wave, peak current output up to 6 times, the AN61 series power supply is an ideal device for testing the inrush current of the switching power supply. 3.Free wave amplification The AN61 series AC test power supply can amplify power of any wave through the specific external port. The customer can record the actual wave on site using the wave recorder, and then send it to the specific external port of AN61 power supply via the wave generator for power amplification, so that the customer can simulate the actual wave on site to test the product under test.
