Combine 2 Power Supplies Question

[deblen]

Hi,

When one wants to Power Inject with a second power supply of the same voltage, all the information states to not have the positives connected, only the negatives.

If I was to use two 12 volt 350 watt (Chinese) power supplies connected with the positives connected, what would I need to be able to achieve this, or it is not possible.

When I mean what do I need, is there other comments that I might have to solder together from the positives together

Thanks in advance.

Do not do this at all ever.

(unless the supplies are specifically designed for this)

Easiest way would be to break the positive in the lights at the power injection point and keep the negatives connected. Save yourself the risk of either fire, or two dead power supplies.

Are you trying to power only one prop?
You could split the prop into 2 and power each half seperately or use a higher output 12v like a server power supply

Hi, Thanks for the replies.

What I was thinking of was using a 12 fuse fuse board that was rated for 30 amps. Used in vehicle applications. By using smaller fuses I would run one side for one power supply the other for the second, , thus the reason for two power supplies.

Yes this is what i do for some of my boxes but each power supply is feeding a seperate prop or data line. If its a single prop best to as @Notenoughlights suggests
