MPB125 SERIES
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.
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.
• High Power Density in Industry Standard 3" x 5" Footprint
• Power Factor Correction (PFC) Meets EN61000-3-2
• Main Output Remote Sense
• Power Good Signals
• CE Marked to Low Voltage Directive
• Input Transient & ESD Compliance to
EN61000-4-2/-3/-4/-5
