I need a battery charger that will run off of 25VDC. If the circuit is hrx49 in a case then a small fan might be necessary and can generally be powered right off the output of D1. Did I get it right that there’s 2 ways yo fix it? Request higher bulk rates.

I would like to have your charger to put out 5 to ma. If this can do it, what needs to be change?

Edited February 14 by marcelv. I hope you will maintain it.


It sct fully automatic and will charge at a rate up to about 4A until the battery voltage reaches a preset point at which it will switch to a very low current float charge. Can I get my instruments re-calibrated and is it necessary?

Not to mention the schematic is drawn in such a weird uncommon way for todays standards to understand. Top Brands View All Manufacturers.

Automatic 12V Battery Charger

Yes you’re right, unfortunately I’ve tried with a modern 2N, apparently with the same features but it does not work properly. Total Price NOK Yall will have to experiment more to see if my theory is correct or way off base here.

Search the forum, or read previous comments. Will try it soon To set up the charger, set the pot to midway, turn on the charger and then connect a battery to it’s output. Can I return the calibrated item if I bex49 not satisfied with the device itself?

An error occurred, your message could not be sent. Please tell me if this charger can be left to charge a battery for indefinined time,or it need other circuits? Can i charge my battery 12v amp.


Please send me the functioning of each components description. Thanks for your replies. You mentioned in the notes that the transformer could be changed to 18V output for charging larger batteries.

The Intertek calibration certificates include:. Depends on the size of the battery.

Fullwave center-tapped or fullwave bridge type may be used as an alternative rectifier to this project. It is good, but i have a 12V-7AH battery. Thyristor TO V 0.

If you have a big battery e. And how long will it take to fully charge the 12V battery? An LED indicates when the battery is fully charged.

In this case, no fan is needed. There is an entire series of BT Triacs.
