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.

Unit recovers when overtemperature condition is removed.
Provided on dual-output models. Up to 4 units can be connected in parallel.
There are some limits for parallel operation. See MPB125 Applications Note.
N+1 redundancy is provided. V2 needs an external isolation diode for N+1 operation.
An external diode is required on MPB125-2003 and MPB125-2005 models for
redundancy on both V1 and V2, or when ordering, you can specify MPB125-2003D or
-2005D which have an internal isolation diode.
Internal isolation diode is provided on V1 for all dual-output models except the
MPB125-2003 and MPB125-2005. Specify MPB125-2003D or MPB125-2005D,
respectively, if an internal isolation diode is required for these models.

NOTES
Remote On/Off
Standby Output
(Option R)
Remote On/Off is a TTL-comatible signal. A logic “high” or open circuit turns the unit on. Reverse inhibit logic can be achieved
by changing the position of the J6 connector. A logic “low” inhibits all outputs except the 5V standby. At remote off, the Power
Good signal will warn the host equipment 2 milliseconds before the main output goes out of regulation. The rating of the
standby output is +5V @ 0.2 Amps. Total regulation is ±5 %. Maximum noise and ripple is 50 mV peak-to-peak @ a 20 MHz
bandwidth.
NOTE: The addition of Option “R” increases the supply width from 3.0 to 3.8 inches. Consult factory for availability.
NOTES:

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
