Re: 1 KVA 240 v transformer output 6v,8v,12 v AC how to test if it can supply 83 amps?



Ok let me explain a little bit more.. on the front panel i have 2
control knobs each one controls voltage and the second one is used to
set a limit on the current...the digital display, displays the actual
voltage and thel current in use..

Today what i have done is the following .. The rear Positive and
negative terminals i connected a piece of copper welding rod about a
foot long its about 2 mm thick.. To me this is a dead short and i
expected to be able to turn up the current so as to melt the copper
rod... However all that happend was that at about 30 odd amps it
glowed red and then the current gradually dropped to about 25 amps...I
admit i am a total novice at electrics but i was sure it would have
took more current than 30 amps...i was sure it would glow white hot
and pop like a fuse?...I then cut the welding rod and tried it at
about 3 inch long this time it glowed whiter at about 80 amps...at 5
volts..Now i have to say im getting very pissed off!!!..So next i
added to the rear terminals a 10mm bolt about 3 inch long .. turned up
the current and i stopped as it went over 150 amps???.... didnt want
to break anything so i stopped increasing the current...Now i am
totaly baffled the PSU can supply at least 150 amps to a big bolt?...
so why isnt it giveing that type of amperage thru my electrolyitic
cell?...

My final test was to use a car battery tester.. this consists of a
large strip of bent metal in between 2 metal prongs.. which has a amp
meter in between it can test 12 v and 6 v car batterys...you normaly
hold the prongs on the battery terminal and the heavy metal strip
gets very hot you can read the ammeter readings to see how good the
battery is..the bent metal strip is coverd with asbestos *** to stop
getting burnt..

Well i connected this battery tester to the positive and negative
connection while my Dad turned up the current control..we stopped the
experiment at about 250 amps.. it was obvious the PSU was working?....

So i am totally gutted have i just wasted a lot of money... on a PSU..

Why ? wont the PSU supply lots of amps to my Cell?....I have read
several patents...the Voltage on the cell ranged between 3.9 v and 4.5
v? at several 100 amps?.. the electrolytic solution is a super
saturated Salt solution..?... I have replicated the exact experiment
yet it wont work?..So surley the PSU is faulty?... but yet if it is
why did it supply 250 + amps in the battery test?.. is there some way
i can force the amps out of the unit?...

If the answer is yes I have wasted even more money .. what power
supply do i actualy need?...I have had several knock backs with this
project.. but this one as knocked me of feet..My friend's say i have
to stop wasting money...but i will get another power supply if i have
to...i wont be beaten...i will just go bankcrupt :)..

Hope you can advise?...
