A Fumbling I Will Go MEGAWATT. Photobucket To Dropbos

One failure. Likely a typo somewhere.

See the can of Raid?

Debugging

I'll work on it.

Physical debugging, mental debugging (mental floss), analog/digital debugging, Mex, you do it all!

Pics have good depth of field, must be a small aperature , or a tiny camera (phone, etc).

Acting like a proton, life is much better.

Can't slow down...

Something may be gaining on me...

??? :h

Head scratching is of little value during a dry run test. To spend a month creating articles only to have them swallowed is discouraging. The true test of interest is a response posted in words as a question.

I ain't into doing transcript back-flips to satisfy idle curiosity.

Edwin Holtzman, my physics professor "If they are merely browsing they will seek no specific answer"

The megawatt issue has been covered so many times, enough is enough. Interested parties are after specific instructions. I am trying to satisfy those interested parties.

So the additional external potentiometer is in parallel with the original. micro pot.

Do you set the micro pot to max resistance or to minimum resistance or does it not matter.

Appreciate the photos, Since Photobucket did their money grab regarding thrid party hosting, I deleted my account and many hundreds of photos stored there, and raise a giant middle finger towards them.

On the Cheapowatt, AND my Meanwell, I completely removed the original micro potentiometer and soldered wires to where the original pot once resided.

Note wind up timer on side and 2-10 turn pots on roof. Red and Green pilot lamps are LED. The case contains two Megawatts and a 50-amp Schottky rectifier

Okay, here is your question. Why 2 Megatts (S-700s I assume) ? Parallel for more power ?

Why TWO 10 turn pots ?

And what the heck is the Schottky rectifier doing ????

Two power units = unity power or Flexibility. In tandem 90 amperes charge rate

Separate:
a) Redundant safety factor. One fails the 2nd can take over
b) Individual voltage controls. Different batteries different temperatures.
c) Schottky rectifier isolates the units. No isolator no parallel operation*
d) Timer on one charger. Allows it to be absorbsion charger with time limit
e) When timer shuts off unit # 1, unit # 2 continues as a float charger no timer

So in essence if there is 6 cells of batteries, the Borg will charge them. Flooded, calcium, gelled, AGM. 12 hour timer can allow for a very big bank. Voltage set-point span 11.7 - 15.44

A voltage adjustment for each charger allows it to bulk charge or float anywhere I set it.

Set the voltage way way back. Start THREE HUNDRED WATT generator. Increase voltage just until generator starts to lug down. Must be increased every half hour. Or not.

Charge batteries 110F? No problem. -35F still no problem.

Important thing is when up to 12 hour timer runs down, 2nd charger set at float takes over automatically. Set it and forget it.

Weak Mexican power? Compensate. Turn voltage down to start off with then tweak up every so often.

*These power supply chargers can not work in tandem. One will shut down. The 500 ampere rated schottky is so huge it absolutely minimizes heat, and has a forward voltage drop of .17 at low or no load.

Timer charging is not critical when it comes to over charging. Who cares if the Borg absorbsion charger runs at 14.7 volts for one or five hours "too long"? The battery doesn't care. I don't care.

The BORG primary use is as a BATTERY CHARGER. Not a converter, inverter or perverter. It is incredibly flexible. And my 12 year old granddaughter works it just fine. She has started cars, charged the family fishing boat battery, then connected it to the Lifeline. Without an error or hesitation.

And Rashneesh the programmer, of Calcutta and the Lucky Dragon integrated circuit company had nothing to do with any of it...
