Hmm I talking to those who see AVR or stabilizer and know the difference and their working and by the way you can google and at least see there pictures so you will know how they look like.
Thank you to you guys i have successfully modify it,I just loaded the 12v rail with 50 ohm 10watt resistor and done,now it perfectly charging and its voltage is adjusted from 7 to 28 voltage.I modify another psu which i got from old P3 pc it is branded Dell power supply of 10watt and can only...
Thank you so much yes the battery is poor now I test i can vary the voltage from 12 to 24+ :wink: but another problem is that when i connect this with 100ah batter at 10v initially it charge at 10 amp but with in a 2 minutes the amperage drop to 2A..it gradually decrease...how is it possible...
Dude I have doubt can we charge with Pc power supply or not??The only requirement is just voltage ? or some thing else? my power supply is AT and 250watt 12v@10amp.
I measured the out put it actually gives 13,8V irrespective to load,similarly when it was at 12v there is only a negligible change when load is connect.I as in battery case it does not charge it seem like a open circuit.
what do you mean by that "it may limiting the current?" and battery is not fully charge it's voltage is about 11.34v.I tried to charge by connecting series bulb but nothing happened similarly I also connect dummy load across +5v and Gnd it just slightly increase the current .12mA to 15mA.:sad:
Well i modify the computer power supply and now it gives 13.8-14.2 volt but the problem is till there!it is not charging the battery just only few milliampere! plz help any idea!
of cource it's a ups and the charging current is in the form of pulsating so that it charge the battery.Now I hold up a DC burshless fan from Pc rated 12V@2.5Amps directly attached to the battery terminals and using clamp meter in order to measure current so at this time it just shows .335Amps...
Nop it's not ripple current as well as not in milli amps it is considerable amount of current that is possibily correct,I checked the current of batties that is connected to the ups and it shows the charging current about 3.11A and you can clearly shows in the pictures that the meter can only...
Well I have the same Question that is asked in the thread."Can I measure AC current with dc ampare meter or DC current with AC ampare meter."
I bought the clamp meter which is desinged to mearsure AC current but I m surprised when it also showed the DC current I googled but could not find any...
Buddy if you have enough time so try to make yourself no doubt you will learn to much I grantee you
but if you don't have just stop Googling and just by a usb or serial programmer it will really save your time and money and consume your time to make and test the programs rather then built a...
Dear all,
I have have my Engineering in Electronics so i deiced to go for MBA i have some confusion regarding to select weather HR or Administration?which one is more appropriate for being an engineer?kindly help me out.
Thanks
