Combining Two 12v DC PSU Outputs for 24v

Another good suggestion, many thanks. Never even thought that was an option. So would this also work on battery backup? I assume so as the input to the booster is from the output on the PSU which remains powered during battery backup. I assume this would drain the backup battery quicker though.

That's great idea. I'll try that but it looks like I'll be buying a new PSU for this. I was just hoping to use the battery backup for the maglock but it's not a security issue so not essential.

That's what I feared might happen which is why I haven't tried it yet! Each output is protected by it's own resettable PTC so not sure if that would offer any protection from doing any damage by trying it?

Combining Two 12v DC PSU Outputs for 24v

I have a 9 output CCTV PSU wall mounted supply. I have several spare outputs and need to run a maglock rated at 24v DC 250ma. Each output on the PSU is rated at 12v DV 2A. Can I link two outputs in series to output 24v DC?
