Application Overview:
MVP Series
MP Module Output Current Limit Characteristics
Originator: G. Fry
Location: Merry Hill
Date: 4/5/00
Description
The current limit characteristics of the output modules of the MVP series are mainly of the
foldback current limit type. The dual output module has a slightly different characteristic, the
auxiliary output is a constant current output.
This note details all of the standard module sizes and voltages. Any in-between voltages will have
a similar characteristic. These results are from actual sample measurements.
The modules are as follows
1E 5V 35A
2E 5V 60A
3E 5V 120A
4EE 5V 10A 5V 10A
