› Looking for a Power Supply for a i Charger 4010 Duo

Yesterday I won a icharger 4010 Duo charger in a raffle at the RC club that I belong to. I went to sleep that night with a big smile on my face.
I woke up this morning thinking about what power supply should I get?
Ny initial thoughts are to get a 48VDC power (with 30A to 50A) supply for no other reason than to reduce the amount of current in the wires between the power supply and the charger, and also to allow for future growth.
I am aware that I may have to get two server power supplies and put them in series in order to get the 48 volts. Having two supplies may be more expensive and complex than a single 24v supply rated at 1200 watts.
I am planning to have a parallel charge board on each one of the outputs ports. Each parallel charge board will have three 6s 2650ma lipo batteries that I will charge at a 1X rate.
So any ideas and/or comments?

Regards, Dave

Whatever power supply you settle on make sure it is high quality. I went through 3, 4010s a few years back because my power supply was occasionally spiking just over 50 volts and frying them. Customer service is pretty terrible from Icharger if it ever goes down. I ended up with a dual power lab 8 and a bump controller. Nothing really against the 4010, but I feel they could have made it a bit more robust at the input to handle a few more volts to be on the safe side. Perhaps it would be smart to stick with a 24-36 volt power supply being as you will not be pushing the charger even close to its limit, you could series 2-3 dirt cheap 12's to get the watts you need.

Power Supplies
Check with DSW here on RR..
I have been running 24volts (1400w) on my 406Duo for over 3 years now..I am running parallel boards on both sides..
I can charge 4x 6s 10,000 mah batts at 1c (40amps) with no problems.
Pretty sure they will do the trick for you!!
Good Luck with your choice..

Ps: I use the heavy duty fused parallel boards from ProggresiveRC.. if you pm me your email I can send you pics of my setup if your interested..

I was using 2 server PS and one died taking out the charger. Whatever you decide, make it one PS.

What kind of monster raffles a charger without including a power supply?

As Dan in post #2 suggested, I find the 4010 to be fragile. It is fussy about being treated properly or it will fail. I too have had to send my 4010 in for service.

I can't say for certain but I think it was from turning on the power supply while the charger was connected. As it is now, I switch on the power supply first, let the output voltage stabilize, and then connect the charger. Using this procedure my charger has been perfectly reliable for at least 5 years now. My power supply will only put out 30 volts max which is well below the iCharger's max input of 48 volts. I believe, in my instance, the ramp up in voltage was damaging.

My Revolectrix Dual PowerLab 8x2 has been permanently connected to my Cosel 48V power supply for nearly 5 years now without issue. In fact, I don't have a switch between the power supply and AC plug. At the field I plug it into the generator and fire up the generator and the power supply comes on and powers up the charger. At home I use a switched power strip.

I always recommend using a single power supply of the desired voltage and never recommend using power supplies in series unless they were specifically designed to be used in series.

A good industrial grade power supply will last a lifetime. MeanWell and Cosel are good and there are many other brands as well. I have a MeanWell 2000W 48V as well.
