LS2090 — LISUN LED Power Driver Tester

The LS2090 is a comprehensive test instrument for LED power drivers per GB/T 24825-2009 and IEC 62384:2006. It measures input characteristics (AC and DC), output characteristics (AC and DC), output start characteristics (DC) and harmonic testing.

AC input: voltage 3–300V (CF=1.67), current 5mA–2.7A (CF=3), power 0.015–800W, PF 0.000–+1.000. Frequency 45Hz–65Hz (fundamental); narrow band 45Hz–5kHz; broadband 45Hz–1MHz.

DC input/output: voltage 3–500V, current 5mA–8A, power 0.015–4kW. DC output also measures ripple wave current (5mA–2.5A).

Output start characteristics: captures lamp voltage and current change curves within 0–2 seconds.

Harmonic testing: total harmonic components 0–50 orders, wave ratio, initial and peak phase angle.

Displacement Factor (DF) testing included (updated from WT2080). LS2090-IEC with additional software fully meets EN/IEC61000-3-2:2019. Usually works with LISUN LSP-500VARC pure sine AC power source and LISUN M9822 DC electronic load. Software runs on Windows 7–11.
