I have an LED light which has a ground wire that I want to test with my power supply. What should I do with this wire if my power supply only has a positive and negative terminals?
Dear friends. May I ask if a 60v 5amp @ 150w bench power supply. Allow me to use 12v at just above 10amps for a diesel heater??? I know I can buy a 30v 10amp supply but my needs will need at times to supply 42v @ 2amps. Any help would be highly appreciated ✌️✌️✌️ Sincere regards, Scott. ✌️🙏✌️
Does anybody have any recommendations for my first power supply I was hoping to get something with oscilloscope I am not rich so I can't buy the £1000 I'm looking at around £150 But I could make a power supply out of an old pc power supply And just buy a scope
*All this is confusing lol. I have a bench power supply that has 30v and 10 Amp. I just want to test headlight assemblies, but I'm not sure how to set the proper voltage, Amp, what's the difference between coarse or fine.
Coarse moves the amperage level up faster (like 1 2 3 4) and the fine knob moves it in smaller increments (1 1.1 1.2 1.3 etc) This is so if you’re hooked up to a motor let’s say, and you want to hit a specific RPM, you could get it close to speed using coarse and than fine tune the power with the fine knob.
I'm not an expert by any means, but some things to ponder. Keep yourself dry, anything under 24v I personally consider safe in completely dry conditions. Osha says up to 50v should be relatively safe in dry conditions not to say you can get shocked or burned still. You even feel even 9v your tongue. In general mitigate physical contact if you can, ppe like good rubber shoes and gloves might not be a bad idea if your not sure. Again not an expert but I've worked a lot on 12 and 24v systems DC. Currently I'm working with 48v batteries and those I'm going to be using ppe
