Default Dentron MLA-2500 Question


As I recall the MLA-2500 ran 2200 volts.

Roger:

Yes that ia about correct for no load. I am running mine off 120 vac, and
the B+ drags down to about 1600 volts at 0.8 amp load. I've seen other
conversions that run off 220 vac, and they say about 1700 volts for the same
load. The voltage doubler capacitors if increased in value, say 330 uf
instead of 125 uf would be better. This however would require adding a
soft-start turn on modification to avoid welding the contacts of the power
switch, or blowing the diode stack.
