Title: Want a DC input for charger Post by: satyagupta on March 14, 2012, 12:07:42 PM Hey Guys i need DC adapter for this charger
http://www.hobbyking.com/hobbyking/store/catalog/Variable6S-2.jpg Input Voltage: 11~18v Circuit power: Max Charge: 50W / Max Discharge: 5W Any suggestions? Title: Re: Want a DC input for charger Post by: roopeshkrishna on March 14, 2012, 12:22:34 PM Satya,please check the input current, for a given voltage..and which battery, means in volts that you are going to recharge..? a 12 volts..?
Title: Re: Want a DC input for charger Post by: satyagupta on March 14, 2012, 12:24:05 PM These are my batteries
ZIPPY Flightmax 4000mAh 3S1P 20C http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=7634 Rhino 610mAh 2S 7.4v 20C Lipoly Pack http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=7305 This helps?? Title: Re: Want a DC input for charger Post by: roopeshkrishna on March 14, 2012, 12:26:32 PM ok..it is better to buy a battery eliminator, in to 14 Volts DC, and with a 2000 mAh capacity..it will be nice with 7.2 and 11.1 batteries..please try to buy a good quality eliminator, with ripple rejection circuits.. :thumbsup:
Title: Re: Want a DC input for charger Post by: satyagupta on March 14, 2012, 12:28:43 PM errr any links from where i can buy?? :(
Title: Re: Want a DC input for charger Post by: roopeshkrishna on March 14, 2012, 12:30:03 PM oh..Satya..no idea..to me..but you can make it one in an hour your own..costs about 300/- Rs.. :thumbsup:
Title: Re: Want a DC input for charger Post by: satyagupta on March 14, 2012, 12:31:00 PM how??? have any tutorials?? will be very happy to make one of my own.. Please pleaseee sir jeee...
Title: Re: Want a DC input for charger Post by: roopeshkrishna on March 14, 2012, 12:32:09 PM wait a little.. :hatsoff:
Title: Re: Want a DC input for charger Post by: satyagupta on March 14, 2012, 12:32:47 PM Jhakassss i am waiting :D
Title: Re: Want a DC input for charger Post by: roopeshkrishna on March 14, 2012, 12:40:38 PM Ok..you have two options..buy a ready made one, or make your own..
to buy, 14 volts, 2000 mAh battery eliminator.. to make, a transformer, rated at 14 volts, without centre tapping. four general purpose diodes, in to IN 5407, or any high Amp rated rectifier diodes.. two 2200 Micro Farad value electrolytic capacitors..must be a good quality ones.. four in to 104 Piecro Farad high voltage disc capacitors.. red L E D X 1 1 kilo Ohms 1/4 watt resistor X1 apropriate cabinet, as box cabinet or a wall cabinet..is up to you.. if box cabinet, an AC cord wire, and a main switch..connecting pin..in your oicture shows a 6 mm power aux Dc pin..make sure it is ok, and quality..circuit is very very simple..follows.. Title: Re: Want a DC input for charger Post by: roopeshkrishna on March 14, 2012, 01:02:37 PM here is the circuit..sorry for poor drawings..will add a good one later..
here the diodes are shown with a band on it make sure its direction as correct..and yellow disca are 104 discs.. Title: Re: Want a DC input for charger Post by: roopeshkrishna on March 14, 2012, 01:04:26 PM still feel tough..? need to add a photographic instructions as steps..? so cool..
Title: Re: Want a DC input for charger Post by: satyagupta on March 14, 2012, 02:19:33 PM Thanks for your time and effort, you have added a bridge rectifier to the output of the transformer nice nice :) i guess i might have this.. will check this out..
Title: Re: Want a DC input for charger Post by: Swapnil on March 14, 2012, 02:31:04 PM Hey Guys i need DC adapter for this charger http://www.hobbyking.com/hobbyking/store/catalog/Variable6S-2.jpg It is easily available in any electronics shop. You can also use a laptop charger/ adaptor. Title: Re: Want a DC input for charger Post by: satyagupta on March 14, 2012, 02:32:45 PM Do i have to say any voltage/amp rating for the same??
Title: Re: Want a DC input for charger Post by: Swapnil on March 14, 2012, 02:35:41 PM Yup. 12V, 5A.
Title: Re: Want a DC input for charger Post by: satyagupta on March 14, 2012, 02:39:34 PM Thanks :) will try to find that out..
Title: Re: Want a DC input for charger Post by: sushil_anand on March 14, 2012, 03:21:38 PM The diodes in the negative side are reversed! The cathode (banded side) should be towards the transformer end.
Title: Re: Want a DC input for charger Post by: roopeshkrishna on March 14, 2012, 03:58:44 PM Thank you sushil sir..i drawn in a hurry,now replaced.. :salute:
