Re: Gecko wiring question

Jerry,

Find a way to lower your power supply output. Your voltage will
likely fall when you put a load on it, if it is an unregulated supply.

Mariss provided the info you are looking for awhile back in this
groups message archive.

Bottom line is there is a reason Mariss chose that 80v max... Like
most other things, electronic parts can work over a range of
volts/amps. But also like other items, the more you push this, the
more likely they are to break; until at some point the "breakage"
becomes catastrophic, and all but guaranteed. (magic White smoke
exits here<G>)

The Gecko drives are "rated" based on component part specs, and a
desired life expectancy. The life expectancy curve established is
then turned into max specs for voltages, amps, etc. From Mariss's
explanation, the drives DO have the ability to work at higher
than "spec'd" voltage. BUT, you will pay the price in shortened life,
possible failure; and I certainly wouldn't expect Mariss to honor any
warranty when the drives are used outside of published maximums!

Hope this helps,

Ballendo
