Description

LISUN Harmonics and Flicker Analyzer Test System includes three professionally matched test instruments: LSHF61000-3-2/3 Harmonics and Flicker Analyzer, LSAIF-503 Flicker Impedance Network and LSP-1KVA-HF Low-Distortion AC Power Source. It is a complete, high-precision, certification-grade single-phase EMC test system that fully complies with IEC 61000-3-2 (GB 17625.1) “Limits for harmonic current emissions” and IEC 61000-3-3 (GB 17625.2) “Limitation of voltage fluctuations and flicker”.

The system employs a high-speed 16-bit AD converter to deliver high-precision, real-time measurement and analysis of key power quality parameters across the full range of AC input characteristics. It supports comprehensive harmonic assessment and automatic limit evaluation for Class A/B/C/D equipment under test (EUT). The system is widely applied to a variety of electrical and electronic products, including household appliances, LED drivers, power adapters, lighting equipment, control modules, EV chargers and other consumer electronic products.

Harmonic Test Settings According to IEC 61000-3-2 and Flicker Test Settings According to IEC 61000-3-3

Test Parameters:
Harmonics Test Parameters (IEC 61000-3-2): Urms, Irms, P, PF, Freq., DF, THDI, THDU, Ipeak, CFI, CFU, I_fund, THC, POHC, Iphs, Iphp, Iphe, Iphpk+, Iphpk−, I60_90pMin, I60_90nMax and 0–50 individual harmonics (harmonic %, current mA, current mA/W). It automatically evaluates harmonic limits, POHC limits, THD limits, phase criteria for IEC Class A/B/C/D equipment and generates Pass/Fail results.

Flicker Test Parameters (IEC 61000-3-3): dt, dc, dmax, Tmax, Pst, Plt. It supports configuration of target voltage/frequency, observation period and period number; monitors voltage steady range, voltage curve, and fluctuation trends; automatically compares against standard limits and generates Pass/Fail results for dt, dc, dmax, Tmax, Pst and Plt.
