Description
(See page 4 for ordering information)
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 5 Cubic Feet per Minute (CFM) forced-air cooling with the exception of the MPB125-
2003 and -2003D which need only 10 CFM for full power. Optional remote on/off with standby power is also provided (see Options).
The MPB125 product line is approved to the latest international regulatory standards, and displays the CE Mark.

NOTES:
1
Maximum peak-to-peak noise expressed as a percentage of output voltage, 20 MHz bandwidth.
2
For MPB125-2003 and -2003D, a minimum airflow of 10 CFM is required to provide the maximum current of 30A on V1.
V1 current can be as high as 25A with a minimum airflow of 5 CFM.
3
Maximum forced-air output power is 125 watts with 5 CFM airflow.
4
Maximum convection output power is 70 watts.
5
V2 is isolated from V1 and can be used as a negative or positive output.
6
12V output’s peak load maximum duration is 30 seconds. Average current must not exceed 5A.
7
Maximum power of 80 watts from V1 + V2 with 5 CFM forced-air cooling. See Application Note #M3 for details.
8
For loads less than 10 watts on V1 + V2 + V3, ripple and noise on the +5V output is Max. 2% peak-to-peak.
