Description
The MPB125 Series incorporates patented high efficiency circuitry, 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.
MPB125 single-output models deliver a fully-regulated output. The MPB125 is rated for convection as well as forced-
air cooling. Full output power is available with as few as 5 Cubic Feet per Minute (CFM) forced-air cooling.
The MPB125 product line is approved to the latest international regulatory standards and displays the CE Mark.
