Hi guys

im new to electronics and still at a sub basic level, i wanted to ask for sound advice before hand

i have a single output switching PSU with an output of 15vdc 3a to power my project

the 2 modules im using both require 15v and both need around 0.5a

how do i connect both on the same power supply?

i have looked at similar projects using a toroidal psu coupled with a bridge rec and large smoothing capacitor but i was told by a friend i can not use a smoothing cap with DC, only AC then rectify it?

some ideas / solution would be great

i can build basic circuits from scematics so a reg/splitter so open to anything


thanks

 

I'm not sure what "modules" you refer to. You said the switching supply provides 15VDC at 3 amps. Just connect this directly (in parallel) to each module.

What is the output from the "toroidal" power supply - DC or AC?

Depending on what you're trying to do, you can put capacitors on AC or DC.

If you're trying to make a DC supply from an AC supply (like a transformer), you'll need to rectify and then filter with a capacitor. Google "full-wave rectifier".

 

Just connect this directly (in parallel) to each module.

+1 Assuming the AC versus DC issue is resolved, just think of your modules as light bulbs being plugged into an outlet. Parallel loads on a single supply.

my psu is DC.

i will connect them in parralel


thanks for the advice
