Friends Some time ago I showed in a video how to take long time backup from UPS by connecting a large battery to the UPS. Many of you may have seen that video, if you haven't seen it, please watch it. Video link will be given in i button or description. Today's video is just a part of that. So let's move on to the main video. Micro Project Bangla
If you install a big battery with the UPS, you get a long time backup from the UPS, but there is a problem here and that problem is that the charging output voltage ampere of the transformer that the UPS has is very low, so if you install a big battery, it takes a long time to fully charge the battery. And so in today's video I will try to solve this problem. Please watch the entire video.Micro Project Bangla
You can see a packet in my hand, there is a charger in this packet. This charger is a 12 volt 5 amp charger. It can charge any battery of 120 to 200 ampere. Let's unbox the charger. After unboxing you can see the charger. You can see the detailed information on the charger. Its model number is FON 1206. Its maximum DC output voltage is 12 volts five amperes. And its AC input voltage is between 100 and 240 volts. See here for applicable batteries 120 volts. Micro Project Bangla After looking at this I find it strange because it will never be 120 volts. I think it's a mistake because it says 12 volts on the package and I measured its output voltage and found it to be 12 volts. The charger's AC input cable looks great to me. Its AC input cable is of good quality for the price. Please subscribe my channel Micro Project Bangla See the plug is also quite strong quality. The length of this cable is about 10 meters. On the other side of the charger is the DC voltage output cable. See that there are two clips attached to the cable. Both clips are of good quality. Here the red cable clip should be attached to the battery positive terminal and the other black cable clip should be attached to the battery negative terminal. This was roughly the initial idea about the charger. There are some other important information about the charger which will be mentioned later. So stay tuned friends Micro Project Bangla. #microprojectbangla
I will run the charger now. So for that I am plugging in the charger's AC input plug to 220 volt current. As soon as you plug in, you can see the indicator LED light with the charger is on. That means the charger is fine. Now charge the battery with the charger. As you can see I have taken a 120 ampere battery. Now attach the red cable clip from the charger to the positive terminal of the battery and the other black cable clip to the negative terminal of the battery. I can see that the indicator bulb of the charger has changed as soon as it is connected to the battery. It has changed color from green to red and the charger's fan is spinning. The charger has a special feature that when connected to the battery, the indicator bulb lights up red and the fan attached to the charger rotates. Again when the battery is fully charged the indicator bulb changes from red to green and the fan on the charger stops. I like this particular feature of the charger. It is an auto cut charging system so once the battery is fully charged, the charge supply from the automatic charger will stop. As a result, there will be no possibility of over charging the battery. As a result, the battery can be used for a long time Micro Project Bangla.
Closed, I will now try to charge the battery by connecting the UPS to the battery and see if there is any problem with the charger or the battery. You can see that I have connected the UPS with the battery. Now I connected the charger. I can see that the battery is charging and there is no problem with the battery, charger or UPS. I charged the battery with it and it did not cause any problem with the battery, UPS or charger. Going pretty well. This charger cost me 700 rupees. You can get it by looking for batteries or electronics stores. You can also buy it from online ecommerce sites. I will end the video here today. Thanks for watching this video Micro Project Bangla.
