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.

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.
