To enhance the rationality and universality of our product model nomenclature, we have standardized and adjusted the model designation method for the HF200W-LSE and HF200W-LSK series products.

Due to continuous product line optimization and technological upgrades, the HF500W-QV series will be officially discontinued starting June 2025. To ensure the continued stable operation of your equipment, we recommend the HF600W-EQV Series​ switching power supplies as the replacement solution. This series maintains core performance while featuring a further optimized design with higher power density and better cost-effectiveness. Free samples are available to experience the enhanced performance.

To enhance the user experience and information readability of our products, Hengfu has optimized the label layout for our switching power supplies, integrating the previously separate labels into a single, unified identifier.

Due to routine product line updates, the HF15W~75W-SSM series will be officially discontinued starting March 2025. To ensure the continuous and stable operation of your projects, we recommend the LSK Series switching power supplies​ as the replacement solution. This series maintains excellent electrical performance while featuring an optimized structural design and outstanding cost-effectiveness. Free samples are available for testing and verification.
