Actually I got ac to 24 volt ac transformer i want to use this transformer for charging by converting into DC line. All comments are subject to approval before they are displayed here, so your comment will not appear immediately.

Ps you are doing a great job. So what this actually means is the circuit is latching the SCR too early as the current across the 2N transistor is ramping up. If you wish to change your cookie settings, or learn more about cookies, click here. Depends on the size of the battery. Not to mention the schematic is drawn in brx499 a weird uncommon way for todays standards to understand.

Please provide as much detail as possible regarding itemThyristor TO V 0. There is nothing at all critical about the SCRs used in this circuit.

I feel I will be cheating on myself if I don’t thank you people for this great and wonderful work! Think it’s R50 but can someone let me know and the value to change it to? This circuit shows that when 12v AC passes through D1 straight away you will only get half the voltage which is 6 volts wcr so how is it going to charge a 12 volt battery?

I have 4 x Amp 12v sealed solar batteries being charged off solar panels during the day.

I have’t checked if there’s something else broken yet, just wanted to get this clear to me. Environmental information RoHS Conform. Item very nice. Newer ones will not work. If you have a big battery e. Philip Wadham converting 24v charger to 12 volt Sunday, May 10, 5: So I figured it out. Hi, if you can provide a charge controller which is charger will automatically turns off the transformer when it reach I have a 24 volt charger no longer used to charge power wheelchair batteries.

Please help me complete this project. All orders for calibrated items are non-cancellable and non-returnable.

Please i would like to know what modifications i bgx49 make to the circuit to enable me charge 12v amps battery at a time. Hey, 2 questions about this circuit. Also, can I use a 18v 1. Please help me out. Seems like it should be reasonably straightforward. You can try 2N for BRX Still looking for a beter solution Also the price of this kit. Search the forum for this explanation.

Can it be a risk of the gates on the circuit board can be burned off, because of the high current? To charge multiple battery types you can mount the pot on the brx94 of the case and have each position marked for the appropriate voltage. Please tell me if this charger can be left to charge a battery for indefinined time,or it need other circuits?


You are making mistakes. Posted February ecr edited.

A description model and identification eg. Did you post the same question on a different forum? Image is for illustrative purposes only. This project is interesting Monitor the charge with a voltmeter until brxx49 battery reaches the proper end voltage and then adjust the pot until the LED glows steadily.

How will I go about this. Hi, How can we add the 12v battery charger to the inverter to continue to charge the batteries while converting power from the battery to v.

T1 is a transformer with a primary voltage appropriate to your location V, V, etc. If the battery voltage drops again the charger will begin charging until the voltage once again scg the cut off point. Is it the normal state of operation or do I need to adjust Pot to glow it continuously.

And how long will it take to fully charge the 12V battery? You have to think, Switching power supplies were still in their infancy when this circuit was designed. Sign in Already have an account?
