CONDITIONS/DESCRIPTION
Full Load, 230VAC. Varies with distribution of loads among outputs.
(Minimum efficiency reflects that of MPB125-2003D and -2005D models.)
V1 + V2 + V3 for MPB125-4XXX and -3000.
V1 for MPB125-2XXX for full regulation on V2. All models operate
at no load without any damage and meet all specs on V1 above 0 amps.
Full load, 20 MHz bandwidth.
At 5 CFM forced-air cooling. See Application Note #M3 for details.
Convection: Consult Factory
Output voltage overshoot/undershoot at turn-on.
Varies by output. Total regulation includes: line changes from 85-132 VAC
or 170-264 VAC, changes in load starting at 20% load and changing to 100% load.
Maximum deviation due to a 25% load change with unit at 75% load.
All models except MPB125-2005 and -2005D.
Model MPB125-2005 and -2005D.
Time required for initial output voltage stabilization.
Time required for output voltage to rise from 10% to 90% except for MPB125-2005
and -2005D.

Overload Protection
Fully protected against output short circuit or overload. Automatic recovery upon
removal of overload condition. MPB125-2003, -2003D -2005, and -2005D latch OFF if
overload occurs on V1 which requires an AC reset.

Remote Sense (Note 2)
On models MPB125-4250 and -4350 remote sense is provided on
Triple & Quad Output Models the 2.5 and 3.3V outputs, respectively.
MPB125-3000 does not have positive remote sense.

NOTES: 1) For MPB125-2003, 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.
2) -Sense must be connected to output common or load common for proper power supply operation.
