I had a PCU-3 (water2gashawaii) "50 amp" on my 12 amp HHO cell on a 30 amp fuse. Two times in a row the unit failed. To date the company has not refunded my money. I am out close to $50 in multiple shipping charges sending it in for repair, back to me and then back again. They have not returned the unit back to me so I can repair it elsewhere. Very fraudulent!!! The State of Hawaii business registry has Hydrogen Fuel Systems listed as "Not in good standing".
@water2gashawaii OK because my capacitor that I got from a microwave was only a couple of micro farads. Also what gauge and how many turns of wire are you using on the secondary of that MOT.
using just 20 windings you get huge current. how many amps is your bridge rectifier rated for? i have a rewound mot that puts out a calculated 23v @45 amps. 12v must have 83A if im doing this correctly...
@water2gashawaii So the parallel rectifiers work well, I am making a power supply but have blown up a few rectifiers, I am thinking about 3, 50 amp rectifiers in parallel attached to the same heat sink.
I have heard horror stories about rectifiers in parallel, supposedly since the V drop is not equal, one will blow up after the other, However I have seen some supplies such as yours that use the rectifiers in parallel.
@legogunguy001 yes they do ok as long as you don't push them. I rarely go over 30 amps, and these are 30 amps each. I did burn two of them up when i hooked up a cell that drew too many amps. I didn't get a chance to measure the amps, but they started smoking big time and making that 60 hz hum before I could shut it down. Not fun.
ive watched 3 parts of this series here and you have failed to explain why the hell you are putting all of this crap together ! good production of what ?? and we dont need wise ass comments like "we ought to know" i design SMT memory for hewlett packard and i dont expect people to know what SMT means!!?? (surface mount technology) so tell us brother what the hell is this contraption??
@ssleslito its basically a power supply. Microwave oven Transformer steps down the 110AC to 12 VDC because of the bridge rectifiers. Production is referring to the amount of gas the cell is producing of HHO or the gas created from H20 when it is electrolyzed and allowed to be mixed.
@ssleslito production of hho... did you take any chem coarses at all? the power supply sepperates hho(h2o(water)) into h and o (hydrogen and oxygen). honestly i know how you feel, but this is kinda self explanatory...
At 30 amps we are outputting about 2.5 LPM. The bridge rectifiers can only handle 35 Amps before failing. Although I have doubled them up here to allow up to 70 amps, I haven't pushed it that far because I don't want to blow the rectifiers.
I like your idea of using a MOT. Can you do a video on how you did it? How you figured the output? and how you wire it using the FWBR and microwave capacitors? - - Thank you.

Are these capacitors smoothing the output from the mot. Just asking

@legogunguy001 no, they are pretty much worthless. HHO cells don't need solid level dc anyway.

to get the secondary out fast you will need a drill and it would take just about 20 minutes and it's out :D

@123324ben you get a rectifier that can handle the load. I currently have 2 30 amp rectifiers in parallel

OK thanks I plan on running at around 50 - 60 amps, I have a huge heatsink though so hopefully that will help.
Thanks for the reply

@ReiMomo HHO is the popular term of Hydrogen and Oxygen gas that comes from the Hydrolysis of Water (H2O)

@u2btchr I would but it took 2 days to get the wiring out of it, I don't look forward to doing it again, lol.
