Product Change Notice: Cooling Plate HS-656 Can Be Used on PHP-3500 & UHP-2500 Series
With a view to provide customers more options on water-cooling PSU solution and flexibility in product design, MEAN WELL chose UHP-2500 as a new member to water-cooling power supply family. In order to offer water-cooling PSU and cooling plate as a complete solution, we have implemented changes on HS-656 by adding new mounting holes to fasten UHP-2500 series. By such product change, it allows PHP-3500 and UHP-2500 series to use the new version (R1) cooling plate as a common part.
Should you have any further question, please contact your MEAN WELL sales representative.
