Onderwerp: Re: 1 1200 mA Power supply

Hi

when each of your 3HE has its own power supply you should be fine, as
each can run 1200mA on +12V as also on the -12V.
you do not add the +12V with the -12V to get the maximum current draw.

the calculation of the current draw should be done with maximum draw. so
hopefully there will be no peaks above the calculation.

i have a case with a A-100PSU2 that draws aroun 1100mA from modules and
runs ok. well it can get really hot in this case and i heared that maybe
the power supply last not that long doing this...

some people say good practice is to have 1/3 or 1/4 headroom on the
current consumtion.

regards
felix
