Product No: LS2090
LS2090 LED Power Driver Tester is designed for the standardized performance verification of LED module power supplies. It can be integrated with LISUN LSP-500VARC pure sine AC Power Source and LISUN M9822 DC Electronic Load to form a complete testing solution. The system includes PC-based software (available in both Chinese and English) and is compatible with mainstream Windows operating systems.
LS2090 LED Power Driver Tester is designed to conduct comprehensive AC/DC performance evaluations of LED drivers. It captures transient operating characteristics during power-up, performs harmonic and displacement factor analysis, and automatically generates complete test reports. Serving lighting manufacturers, third-party testing laboratories, and research institutions, the instrument provides reliable and consistent data for performance benchmarking, failure analysis, and compliance verification of LED drivers.
