Nope, this is a 15 volt supply, You need 44v for the PM1000 modules.
Does anyone know how much current one PM1000 input module will eat? I'm racking up a couple of these too and I'll need to start building some supplies soon too. I'll probably put 4 in a box and I'm wondering if I can use the TL783C regulators i got from maxwall for this.[/quote]
i recall reading somewhere when i was researching the whole PM-1000 thing that the typical current draw for an input module was around 100 mA.
v, you are going to need 44 volts and 48 volts - you can just tap off of the one output connector of the power supply and power both modules no problem. -/+ 15 volts has no business being anywhere near those modules so get that idea out of your head.
you can get 44v and 48 v from the same output - it's pretty simple to do, but you need to run something like 4 or 5 diodes in series to step the voltage down to 44 volts (you could just use a little perfboard to mount the diodes on, i think on the krashjones site, he just wired them straight together and put some heatshrink over them). just connect the phantom power for both modules straight to the power supply output directly, then connect the diodes to the power supply directly. all to the same point - then the 44 volts for both modules would go to the other side of the diodes.
anyone who's done this remember what diodes were used?
