New MMCCalc2 released



Hi All,

I have improved my MMCCalc program.  

A number of people wanted to be able to match the MMC to their
transformers.  While this is sort of an art, I was able to put in the
maximum LTR style cap calculation in so people can either select strings or
reduce the number of strings from there.  simply type -1 instead of the
desired value you want to have the program find the LTR cap size.  The
program is at:

A sample output is:

-------------------

The program underlines a "safe" MMC cap array and uses those smiley faces
on the right to judge voltage and temperature.  You can often go a bit
higher in the chart so save money with added risk (EMMC).  I actually use
the 5 x 10 configuration above which is high stress voltage wise but my
EMMC was meant to test that (it works fine).

The program is set up for Panasonic caps but the #300 lines can be easily
changed for others cap types.  It is just and old MS-DOS BASIC program so
it is simple to change.

Glad everyone likes this program so much!  Even I am amazed how much it can
do for being so simple...
