LS2090 LED Power Driver Test Instrument is the comprehensive test instrument for LED driver power which is according to GB/T 24825-2009 and IEC 62384:2006. It can measure the following parameters: input (AC&DC), output (AC&DC), output start (DC), harmonic and displacement factor (DF).

The LS2090 usually works with LISUN LSP-500VARC pure sine AC Power Source and LISUN M9822 DC Electronic Load. The LSP 500VARC provides constant adjustable standard power for the driver under test, and the M9822 is used to simulate the LED source. The software can run on Win7, Win8, Win10, Win11.
