Thanks Mark, For your quick reply and shipping. Received my supply here in NS. Canada , today. Now for an Icharger 306-B, I think.
Thanks...Matt

Sounds great Matt. Glad it made it through customs swiftly!

Let me know if there's ever anything else I can help with.

Regards,
Mark

PM Sent with noob question!

With the iCharger 4010 coming up, it would be convenient to connect two of the 24V supplies in series. Is that possible without further modification?

Jahn,

Connecting two of the 24V supplies in series would require separation of the DC return from chassis ground on the second supply that has its DC return connected to the +24V output of the first supply. The power supply will shut down if this is not isolated.

Also, since the supplies are actually ~25 volts, connecting two in series would be at the limit of the input range of the new 4010 Duo.

I have assembled a few 48 volt supplies on request. One purchaser indicated that he had pre-ordered a 4010 Duo. I adjusted the output voltage to precisely 48 volts on these supplies.

If interested, I could assemble a fully isolated 24V supply with lower output voltage that will easily work with an existing 24V supply.

Regards,
Mark

Ordered a 24V with the EC5 connector for my PL6. Thanks Mark!!!!!!

Your PS will ship in the morning Pat!

Thanks,
Mark

She arrived today Mark. Thanks for your great service!!!

Pat

Mark - many thanks for your prompt and helpful communications as I configured my field and bench setups with your 24/12 Volt convertible.

I ordered this past Saturday and it arrived today, Tuesday well packed and sound. VERY clean job on the convertible and it works quietly and stably driving both a Power Lab 6 w/para board at 24VDC and a DuraTrax ICE at 12VDC without missing a beat.

Thanks again!

Thanks Mark. Is there any particular reason this is not done already for the 24V option (separating the DC return from the chassis ground on the second supply)?

Jahn,

Since some chargers have chassis ground and DC return at the same potential, I feel that it is prudent and safest to also have chassis ground and DC return of the power supply to also be at the exact same potential whenever possible to prevent current flow and possible charger malfunction or damage should they come in contact while charging. I discussed this with several power supply experts that I work with a few years ago and they agreed that my reasoning and thought process were sound and would produce the most predictable and safest end result.

Discussions among the brightest engineering minds here on RCGroups support my reasoning and also agree that maintaining DC return and chassis ground whenever practical will yield the most predictable result. As such, configuring my power supplies in this fashion has always been my standard practice. I am aware that others have a more cavalier attitude toward the success of those who purchase their supplies but I personally prefer that those who choose my supplies to be 100% satisfied.

Regards,
Mark

Thanks Mark, makes perfectly sense!

Mark,

What is the maximum amp output per port? I understand that these PS are rated at 47 amps, but is this figure a combination of 2 or 3 output ports, or can one single port put out 47 amps? If so, at what voltage? Finally, is the 47 amp rating valid for 110V ac input through a 15A breaker, or only for 220v input?

Thank you in advance,

Sorry that I missed your query! The notification system appears to be malfunctioning.

With jumper removed, the PS can output 47A on each of the two 12V power supplies. One supply will have a 47A port and the second will have two ports with total 47A capability. With the jumper installed, the supply can provide 47A at 24V.

The full power output is available on standard 110V / 15A service so no special circuit is required. The included Y-power cord requires only a single outlet.

Let me know if I may assist further.

Thanks,
Mark

Wow, these look great and so does the price!

I'm waning to build a portable charging case in the Pelican Storm 2300. Ideally I would like to power 2 Powerlab 8 chargers. Due to space in the case I may have run 1 Powerlab 8 and 1 iCharger 3010B instead. So, it looks like I need something with at least 2000 watts. Do you make anything larger?

I'm very serious about ordering, so if you could give me a few options or would even like to discuss this further, shoot me a PM.
