RIP resistor (Peak current adjustment)
RIP resistance limits the maximum current supplied by the converter. For the calculation see the
following table:
Example: on a converter 7/14A, inserting a resistance RIP 150Kohm the maximum output cur-
rent will not be 14A, but 10.5A
4.5 Ramp time adjustement
The product is standard setting with this feature is not enabled (solder bridge S3 open)
To enable the ramp acceleration close the solder bridge S3 and insert the RACC resistance.
NOTE: The product comes standard with mounted 470ohm resistance value (0.8 sec ramp)
Ramp disabled (standard setting)
