AW: multiple power supplies in a modular

[Barry L Klein]

Ooops, forgot:
600 watt peak pulse power dissipation
5V - 170V or so spec'd voltages available
steady state power diss. 5W
I probably shouldn't too specific as to what we use.  But they come in
larger and smaller packages/capabilities and some sources include World Products, SGS, Semtech, and others.  Mouser has the SGS ones.

> As a result of my work, we put TVSD's across the drive supply lines.  These will clamp any overvoltages.  You might want to try these things on your supply lines etc.  They seem to be worthwhile.  Definitely have improved reliabilty of the product.  And I think only ours have em....(plug)  :-)

Very interesting. 
But I have some questions.
A TVSD is also called varistor, i.e. a polycrystaline semiconductor
device with some defined breakdown charcteristic (what do the letters
stand for?)?  What are the data of the devcices you use?  Breakcown
voltage, max. current, what is the supply voltage these device have to
protect.

Please some answer.
