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 MPB125-2003DG 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 MPB125-2003DG, 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 V 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.
OPTIONS
SUFFIXES TO ADD TO PART NUMBER
RoHS lead solder exempt 1
No RoHS suffix character required.
RoHS compliant for all 6 substances
Add “G” as the last character of the part number.
Current Share (Option D)
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

Remote On/Off Standby Output
(Option R)
Remote On/Off is a TTL-compatible 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
