Nov 02, 2013, 02:30 PM Yes, those are all great points. Thanks Gregor99. And just to point out, that would be 3X12.5v supplies PER SIDE so 6 total and you would want them on separate wall circuits. Latest blog entry: For sale \$114.95 24v 47A Power Supplies!
 Nov 02, 2013, 02:40 PM Registered User Are you suggesting 6 separate 120V AC circuits?

3X12.5v is the voltage and can be shared across both channels. It does not change when powering the channels separately. Current however would be 40 amps per channel, 80 amps total. Difficult, but not impossible to do. You would likely need to run some of the supplies from separate breakers.

Lol, no, no...I was suggesting 2. Three on each. Although, that could be too much if you max out the power supplies. A Power24+ power supply, which is 2x12.5v, at max gets up to about 14 amps input on 115VAC. So if you are on a 15 amp breaker you COULD blow a fuse with 3. I imagine most people will not be maxing out the power supply, and some have 20 amp breakers in their house. But I guess if it is too much for two you could always split it up on 3 circuits. It would be easy enough to do, you just might have extension cords strewn out everywhere.
 Nov 02, 2013, 03:37 PM Gregor99, you are right, but I was referring to 6 power supply units because the maximum amperage per power supply is 47amps. So I am suggesting 3 in series on each side, 6 total individual power supply units. That would make 37.5v per side and a max of 47 amps per side or 94 amps max in total (talking about the limit of the power supply for the input power, not the out put power of 40 amps per side of the charger). I am sure there are other power supplies out there that could go to 80 amps but I am working with supplies that go to 47 so I am trying to figure out the best configuration given that.

I'll have to think about that one. Here's the challenge. Charging a 6s pack at 40 amps, you'll be pulling roughly 30 amps from the supply. 47amps is a bit overkill in that scenario. But with a 50v supply you'd only be pulling about 23 amps per channel, or 46 amps total. It would seem four supplies would be a better fit than 6 supplies unless you want the overhead or need to charge at 7s or 8s.

I have four of the DSP-600PBs. When I get time, I'll set up the config and give it a test run.

Good, six circuits would be impractical. Even three separate circuits within reasonable proximity may be tough for some. Another thing to consider is weight. How much does each 12v power supply weigh?

 Nov 18, 2013, 12:17 PM Registered User I assume this means they're ready to ship out to the dealers now? How about a side by side size comparison of two PL8s vs. one DPL8?
Nov 18, 2013, 09:24 PM
Here's the DPL next to my two PL8s. The camera angle in the first image makes DPL look a little wider than the two PL8s. But the DPL is actually 15mm more narrow.

 Nov 18, 2013, 10:42 PM Registered User Look great! Thanks for posing the side by side comparison pictures. The smaller size of the DPL8 will give me some additional space in my charger case. All in all the DPL8 will be a perfect fit.
 Nov 19, 2013, 10:02 AM Registered User Wow! I did not expect it to be that much smaller. Very nice Last edited by tulz43; Nov 20, 2013 at 09:59 AM.
 Nov 19, 2013, 07:09 PM Registered User Nice indeed. I can't wait to get mine.
 Dec 02, 2013, 05:46 PM Registered User Is the DPL8 CCS available? I checked the website, but didn't see it.
 Dec 02, 2013, 07:22 PM Registered User It should be but I couldn't find it either. There is a beta test version but it is only available to beta testers. You cannot use the PL8 version either. They are different. Glen
