A Zhongshan-based export-oriented lighting company sells its products to countries worldwide with varying voltage standards. Previously, they needed to stock multiple power supply models, which resulted in high inventory and management costs. Our wide-voltage input LED driver supports a full range of models and multiple times the nominal LED power load, adapting to complex power grids and enabling "one device for global use." After adopting this solution, the customer reduced their inventory by 60%, achieved a failure rate below 0.2%, and successfully expanded into Southeast Asian and South American markets.
