Since the topic of charging car batteries is always relevant, I want to tell you how to make the charger from the computer power supply.Special complexity manufacturing technology is different, but you can always recharge the battery if necessary.Yes, and you can make the device yourself at home.
PC's power supply will suit almost any power which would be even a hundred and fifty watts.When you pull out of the system unit, this unit, you will see a bunch of wires.All you need them.Cut off all the excess so that only the output voltage positive lead of twelve volts.Then you need to unsolder resistor whose function is to reduce the voltage to twelve volts.It was discovered quite simple.It passes through the circuit wires necessary to us to chip through two resistors.I'm not sure exactly, but, most likely, this pattern is observed in each power supply.
place of the removed resistor solder pot, its denomination should be withdrawn detail below.This is necessary to ensure that the charger from the computer power supply allows you to adjust the current.Our goal - to achieve the output voltage of fifteen volts, and that the current range may vary from zero to six amperes per hour.As you know, these indicators are ideal for any battery, and our simple charger will also be able to provide them.
Go ahead.The power supply contains only one green wire, which serves to switch.We have to solder it to the body to minus.With regard to the fan, it must be deployed in such a way that air is sucked inwards.You will also need to buy some ammeter and add it to the chain.On it will be possible to obtain information about the current strength of the current is fed to the battery.
tell you exactly how I got the charger from the computer power supply.The new pot, which was soldered in place of resistor, I was attached to the housing.Ammeter I attached on the opposite side.For clips that cling to the terminals, I used metal clothespins.They are well-conductive and have a good adhesive force to stay on the terminals.You can also purchase a special so-called crocodiles.Some people have successfully used for this purpose, special-clothespins clips curtains.
So, I propose to summarize the results of this scheme, namely: what are the pros and cons will have our battery charger from the power supply of the computer.The advantages are that you do not have to spend any funds for this purpose.I hope some old power supply from your computer you will be able to find.Because these devices are used pulse transformers, the entire structure will not be as bulky and heavy as a traditional full-time.As for the disadvantages, it is only one.You'll hear the noise from the fan.
