xavier4or 0 Posted November 3, 2014 So I ordered a "18 Channel Output Port 24V AC 200W CCTV PTC Fuse Distributed Power Distribution Unit" from amazon and it is putting out ~26V to 26.4V on the various ports. Is there an easy way to put additional load (ie hook up something) to either put additional load on the power unit or a way to siphon off ~1V to 2V inline with the cable to the 24v device. Thanks. My alternative is just to return it and order another one that is working properly. Share this post Link to post Share on other sites

Also it depends on how good your volt meter is Share this post Link to post Share on other sites

xavier4or 0 Posted November 3, 2014 Well I have to say thank you. I wasn't originally thinking about the volt meter accuracy. I had 75' 18 awg cable run from 24v power box to the device. But I was getting power input failure (red flashing light...). Well after a couple of hours of trying to figure out how to decrease the voltage out of the power box - I finally said screw it - let me move the power box much closer (about 20' away). And it works now! I double-checked the power from the power box and from the cable into device (it was still around 26V measured) - but I guess I need a better volt meter. Or maybe it was user error - but I did triple check. Woohoo! Share this post Link to post Share on other sites

Well, depending on the type of cable and the draw of your device, you could have had a large enough drop in voltage from your power supply to the device. Glad you got it sorted though!

xavier4or 0 Posted November 5, 2014 Ok, I think my 24v power supply is over-supplying the device – but here is where I am at: 1) 24v power supply, 75’ 18-2 AWG = No Joy (flashing red light on device) 2) 24v power supply, 75’ 18-2 AWG + 100’ 18-2 = No Joy (flashing red light on device) a. Note I originally thought I was over-driving the device so added so additional wire to introduce so voltage loss 3) 24v power supply, 25’ 18-2 AWG = Joy for about 5-10 mins (then flashing red light) a. I moved the power supply much closer to the device b. And I am guessing that I am right on the upper edge of the power supply tolerance. Maybe after a few minutes when the transformer is on – there could be additional voltage being supplied? 4) 24v power supply, 25’ 18-2 AWG + 20’ 22-2 AWG = JOY! a. Running strong for 24 hours now. b. I introduce some 22 AWG for additional voltage loss which seemed to be working Thoughts on this? Since it is working – I am not complaining but wasted several hours running the original 75’ 18 AWG from my networking closet to the device. Share this post Link to post Share on other sites
