Ha! Are you still having brake light issues on the 40?Looks great, Cim. Now come over and clean up my wiring!
It’s a Pyramid PSV-300 DC power supply. It’s been very handy.Cim, what are you using for a 12v power source for all your wiring testing?
The other thing I don't like about it is when you turn it off it doesn't cut the circuit. It winds down. So far for my bench testing it has been great. No more lugging a battery around or using a 12V Dewalt battery. Although the 12v battery does work great for quick tests on stuff.Did some searching and found these reviews on the Pyramid unit: https://www.eham.net/reviews/view-product?id=7154
They're powering radios, so the RF interference is an issue there. That seems to be a deal with the switching power supplies. The alternative is the weight, heat, and lesser efficiency of a linear power supply. Again, these would be more issues for something powering a unit (such as their radios) constantly than a test bed which is on for minutes more than hours. A filter could be added if you're regularly testing audio equipment.
The power switch on the neutral instead of the hot could easily be rewired. The comment about the 30A being peak power and more properly rated 20A could be an issue depending on what you're testing.
Certainly a rabbit-hole to go down... Possible options would be meters and adjustable voltage. I've had some issues with items that didn't work at lower voltages, so that might be something useful for testing. Of course, it becomes a question of price vs. function. You can spend a pile of money on it or get something that serves the purpose and be done with it.
That could work. I think I will make a external switch to cut power instantly off. No worries now since I only test one circuit at a time by removing all the fuses in the box except what I’m working on. When I get to the point of firing up the whole harness I want to be able to cut power instantly if there is an issue.I wonder if the "winding down" would change if you reversed the switch to cut power instead of neutral?
I pulled the inverter from the Matrix as well. It's plug in play once a relay is added.Cim,
That inverter is all-in-one or do you have to connect it to an external inverter that take the 12VDC and converts it to 110AC?
It was held up a day in customs. Other than that it was all good.Gorgeous. No shipping issues I see!
