To address the growing demand from end customers for CANBus and PMBus communication functions, MEAN WELL has implemented functional upgrades for the UHP-1500/2500, PHP-3500, and HEP-1000 series.
Following this upgrade, there will be differences in functional terminals and product appearance compared to previous versions. Any additional cost resulting from this upgrade will be fully absorbed by MEAN WELL, and product pricing will remain unchanged.
After the upgrade is implemented, there will be a transition period during which both previous and updated versions may be shipped, depending on factory inventory status. If you have any questions regarding this product change, please refer to the latest datasheets published on the MEAN WELL official website, or contact your MEAN WELL sales representative or authorized local distributor.
