Power supplies 12v or 24v plug and play

12volt 47 amp 564 watt,
24volt 47 amp 1130 watt.
I am using two in series for 24v on my lab 8, they are very stable, rock solid,
They are set up ready to go with 4mm outlets and power cords.

Heres a close up of the bussiness end of the power supply.
You can see the 24v model is double wrapped, comes with jumper to allow 24V. as you can see you can use 2-12v and 1-24v at the same time. 2-12v top row , 24v bottom row, or remove the jumper and you have 4-12v outlets. With the jumper in place you also can use the out two far out side connections for two 24V outputs. These power supplies are rated at 47 amps. I have personally abused my test setup, just to see where the fail point is. I have had my Lab 8 with 6-5000 3S @ full 40 amp charge and a cellpro 10 with 2-5S running wide open. I'm still using this power supply with no problem. Just because I did this for testing purposes,,,,,,,,,
I DO NOT RECOMMEND GOING OVER RATED OUTPUT!!!

Singles are 12v and white $55 shipped

Doubles are 12v and 24v and black $110 shipped

These are 100% ready to use. Plug and play.

I am a noobie here but have lots of 100% good trader rating on RCG, RCU, and ebay

How are you handling the grounding issue? Are you essentially not handling it and insulating with the cardboard, or are you making an internal modification of some sort

Yeah, grounding is key. When i made up my power supply using the same DPS-600PB units I insulated the relevant PCB mounting stud and cut a couple of wire jumpers so that the second unit in the series pair could be floated at +12V while still having it's case grounded to earth.

The 'hope for the best' solution is just to disconnect the earth on the second unit but that way if you get a fault then you could be electrocuted, which isnt very nice at all:(

Not an issue if you are just using a single 12v unit of course.

jrplane,
I like the way you have used female bullets to hook up to the hot swap connector, much neater than soldering in wires.

Hi guys,

Yes these have the DC ground floated, There is no cardboard, however there is a this peice of foam between them, strapping tape to hold them secure. Then finally wrapped into one nice package. These things are solid! Not like some on the net.
