Learn how to repurpose your old uninterruptible power supply (ups) unit and transform it into a reliable 12v battery charger. this guide provides step by ste.
How To Make Ups Transformer To 12v Battery Charger At Home Up To connect the components and build a 12 volt battery charger, follow these steps: connect the transformer’s ac input to a power source. connect the transformer’s ac output to the bridge rectifier’s input. connect the bridge rectifier’s dc output to the filter capacitor’s positive terminal. Thank you for watching!how to get 12v from ups transformer, how to battery charger at home, ac to dc converter ponents: 1. ups transfomer or 12v step down. Step 1: stuff i used. dc to dc step down converter click. alligator clip click. multi meter click. laptop charger. dc to dc step down converter. it's will convert 19 volts from your charger to 14 volts to charge the battery. it'll provide constant voltage and constant current. ( very necessary ). Step 3: connect the charger to a battery and place a digital meter across the battery. adjust the 1k pot so the relay drops out as soon as the voltage rises to 13.7v. place a 100r 2watt resistor across the battery and watch the voltage drop. the charger should turn on when the voltage drops to about 12.5v. this voltage is not important.
