The MPB125 series is a high-efficiency switch power supply with high power density and active power factor correction (PFC) to meet the requirements of networking and data communications systems as well as commercial and industrial configurations. Dual output units deliver a regulated main output plus a second 12V output for fans or other system functions. Multiple output models provide tightly regulated DC power in a variety of configurations. The MPB125 is rated for convection as well as forced-air cooling. Full output power is available with as few as 130 Linear Feet per Minute (LFM) forced-air cooling. The MPB125 product line is approved to the latest international regulatory standards, and displays the CE Mark.
