I've put two of these in parallel, they didn't share load correctly, and one set of fuses blew on one of them. Nice to see the large diodes and resistors working.
Hey I have 10x40 Amp switching power supplies in parralel. I'm trying to get a good load sharing system. Can you point me in the right direction on any info?
Mike, you could try to connect at a minimum a .01 ohm 50 watt resistor off each PS positive rail (one resistor per PS) going to your main positive terminal. Note you will experience a .4 volt drop with .01 ohm. If you parallel two .01 ohm at each supply you will have .005 ohm resistance and a voltage drop of .2 volts (better) and 100 watts to dissipate the heat vs. 50. Just keep this in mind when you are adjusting your voltages. The way this works is each PS is isolated by the balancing resistor and they can't see themselves and when a load is applied each will share it equally. Here is a video by RF man explaining this network. www.digikey.com/product-detail/en/te-connectivity-passive-product/THS50R01J/A132078-ND/2366771 Here is an example of this resistor www.digikey.com/product-detail/en/te-connectivity-passive-product/THS50R01J/A132078-ND/2366771 73s and best of luck.
So rf man is great. I'm still working on calculating the whole ohms law thing to figure out what I'll need for resistors. I understand it needs to end up at .1 ohm but I need to figure out how many watts each resistor needs to be. I have to order an army of resistors for a monster dummy load I'm building so I wanna order them at the same time. These switchers are 30 amps at 15 volts and that's right where I'm gonna run em. Im still figuring it out but if anyone wants to chime in and help me understand how you come up with an answer I'd appreciate it

Just don't say " Bob's your Uncle" or I might lose it! LOL
Sharky is that a 7300 radio
Looks awesome looks like ill be getting me some of these
What party USA you located my friend
Why not just a flatpack 2 3000 and a pure sine inverter

DID YOU CHECK TO SEE IF THEY HAVE A CURRENT SHARING WIRE OR CONNECTION ?
@@flhusa1 no they are just the ica 40 Amp switchers. You gotta set up your own load sharing I'm I'm pretty sure
@@baltimore_amp_repair thank you for the great Info

You the man mudducksharky!!!
👍🏻
Cost of each module?
9 to 15 bucks
LOL... the fan costs that much.
Nais work. Men hamach it's cos want o daguan
Cool
