Best thing is to order an old part manufactured in the late 80ss and try that. Adding the diode would prevent this circuit from working. Also, can I use a 18v 1. Please I need help for their substitute.

BRX49-T – Thyristor TO-92 400 V 0.8 A – DSI

At night I would like this charger to come in via a day night switch and check the batteries are full, if not it must come in and fully charge these batteries, so that they are full at all times. How about 12v 7A 10hr Sealed Acid batteries? It’s on the page about 8 inches above this comment.

I have a 24 volt charger no longer used to charge power wheelchair batteries. Yes you’re right, unfortunately I’ve tried with a modern 2N, apparently with the same features but it does not work properly.

I can guarantee that near zero volts the Q1 was dying anyway and left again at the next half-wave, of course, if the circuit demanded it.

The charger has now been set. Shouldn’t the transformer secondary be at 15V. If rbx49 are cycling the battery AGM or gel then Can you please provide me some check points to make sure that what I have wired is correct.

The Intertek calibration certificates include:. Dear friend I am an ameture in electronics. Have to find the sweet spot My battery was not dead she have 12,7V. I need a battery charger that will run off of 25VDC.

BRXT V A THYRISTOR | Fabian Enterprises Ltd

Is this circuit workable for batteries from 50 to AHr? I hope you will maintain it.

Zcr the detected deviation is too large in relation to factory specification, adjustment of your data logger or measuring instrument will be required.

T1 is a transformer with a primary voltage appropriate to your location V, V, etc. So 4A is too high, do you have any idea to decrease it to around 0. This charger will charge any 12V lead acid battery including flooded, gel and AGM.

No track and trace will be send to the client. It almost has to be re-drawn to understand the circuit better. Edited February 12 by techknight. Close Your message has been sent. Thanks in advance yours,cyprian. In this circuit you suggested 12V ac Transformer, not to mention that the diodes will lower the output voltage also lead acid battery isn’t at 12V even when discharged, its around somewhat If you close this banner, or continue browsing, it means you consent for us to use cookies.

Can I use 12v 5Ah transformer instead of 4Ah? Is your circuit have over charging protection and it is continuous rated? Actually I got dcr to 24 volt ac transformer i want to use this transformer for charging by converting into DC line.

Please explain briefly circuit function of lead acid battery charger. Register a new account. An error occurred login failed. Please stop posting comments hoping someone will write you back.

Ps you are doing a great job. It would be kind of you if you can help to design a charger to charge AH lead-acid battery via solar cell and alternatively main power line.

What do I receive if I choose a calibrated product at Distrelec? Please enter your name and your e-mail address. Search the forum for this explanation. Add diodes large enough to handle the current on the output to prevent battery drain in the event of a power disconnect.

Please give the circuit diagram and working for 6V battery with current less than 0. The answer is the same as before.
