The Laplace Instruments AC2000A is a self-contained single-phase harmonics and flicker analyzer for IEC 61000-3-2 and IEC 61000-3-3 compliance testing. With a built-in LCD display providing real-time pass/fail indication, waveform display and harmonic bargraph, it requires no PC for basic operation — though USB and RS232 interfaces are included for PC connectivity, data archiving and printed reports. In addition to harmonics and flicker, it functions as a full power meter measuring voltage, current, power, power factor, THD, crest factor and phase angle. Inrush current measurement up to 425 A is also supported. For full compliance testing, the optional AC1000 clean power source is recommended for loads up to 1 kW.
