For a quick and simple dual power supply, use two resistors in series connected in parallel with two capacitors. Connect the two ends to the battery or power source and BAM! You have a dual power supply. Typical values for bipolar converters like this are 100k-1M for the resistors and 47uf to 4700uf depending on the current draw of your circuit.
All that is needed to recharge battery cells is DC current. With DC current, electrons will flow back into the battery, establishing the electric potential, or voltage, that a battery was meant to have when it''s fully charged. Components Needed. DC Power Supply; Battery Holder (for battery that needs recharge) 2 Alligator Clips; Battery to be
The power supply itself can tell whether it''s receiving one voltage versus another and can work with both, delivering the correct type of power. Some power supplies are only designed to work with one type of voltage. If this is the case, you will have to get a new power supply or use a converter strip if you have one available.

The ASIN is : B00GY01UMC When connecting 12.5 V battery to IN, the output voltage is 12.4 and does not change when turning
The potentiometers adjust the maximum current and voltage that the supply will deliver. With no load, the supply will produce the maximum voltage that you set. As you increase the current, the voltage will remain steady until the load reaches the maximum current setting, then the voltage will reduce to keep the current constant.
Once the target voltage is close to being achieved, the charger goes into a constant voltage mode and keeps the voltage steady by decreasing current to top off the battery. Once the charging current is down to around 100mA at the target voltage, the battery is fully charged and the charger shuts off.

The next step to setting up your adjustable voltage regulator is to adjust the voltage output with a potentiometer. To give you some context, think of a potentiometer as a volume knob on a radio—in other words, it''s used to adjust and control the output voltage. To adjust the voltage with a potentiometer, you''ll need to:
An AC-DC power supply may have a potentiometer accessible to set the output voltage from the original factory set point. (See Figure 1). Adjusting the output voltage may be needed to compensate for voltage drops
This video shows in detail how to either raise or lower the voltage of a Powermax Converter.Caution: May void warranty from Powermax
Additionally, do not confuse a power supply with a power source. A power source refers to the origin of the incoming electricity, such as an outlet, battery, or generator. In contrast, the power supply converts incoming power into the correct format and voltage required for the device. Power supplies are also known as electric power converters.
To adjust the voltage we have to do couple of steps. Connect the converter with the battery or other power source. Know how much voltage you have inputted in the converter. Set the multimeter to read the voltage and connect the output of the converter to it. Now you can already see the voltage on the output.

A dual power supply is a regular direct current power supply. It can provide a positive as well as a negative voltage and ensures a stable power supply to the device as well as helps to prevent system damage. As many electronic circuits require a source of DC power, the need for dual power supply for certain circuits is necessary.

The fact that a switcher''s supply current draw increases with decreasing supply voltage may in some cases cause battery voltage to drop more "suddenly", but the effect won''t be overly large when using a buck converter for moderate step-down ratio, and it''s a result of drawing less current from a good battery than would a linear. $endgroup$
Therefore, I present a simple modification of an AT or ATX PC power supply to an adjustable bench power supply of 3 - 15V with a proper regulation and an output current corresponding to the original 12V output. The voltage feedback is
Now that you have provided more information, a voltage regulator is not actually what you want. I will go ahead and leave that part of the answer in here for reference though.

A variable power supply (VPS) is a type of power supply that allows you to adjust the output voltage and current to suit your needs. Unlike fixed power supplies, which provide a constant voltage and current, a VPS gives you the flexibility to set the output parameters within a specified range.

Power supplies are usually set to a fixed output voltage to supply an electrical load with energy. Certain applications, however, require a variable generated voltage. For example, in some cases, a microcontroller can be operated more efficiently if the core voltage is adjusted according to the respective operating state.
to Suresh Kumar: Your 15amp power supply can power the leds and the fan together, but you cannot charge the battery bank with it, since the voltage is too low. You need 27.6V to charge the batteries. Can you change the output voltage of the power supply? Then you can set it to 27.6V and connect it to the battery. It will charge the battery.

It would be a good idea to get your Arduino to measure a stable voltage that is NOT its own power supply. Perhaps a 3v battery with a potentiometer attached so you can vary the voltage. Then, because the battery voltage will be stable (at least for a few minutes) you can compare your Arduino measurements with your multimeter.

Before charging a 12V battery with a power supply, it is essential to identify the battery type. Two common types of 12V batteries are lead-acid and lithium-ion batteries. To charge a 12V battery with a power supply, you need to adjust the voltage and current settings of the power supply. Most power supplies have adjustable voltage settings
Adjust the power supply settings to provide a voltage output of 12 volts. Set the current limit according to the battery''s specifications. For most batteries, a current limit between 1 and 2 amps is appropriate. Step 6: Start the Charging Process. Turn on the power supply and monitor the battery''s voltage using a multimeter if available
Understanding generator voltage is crucial for efficient power supply. This section covers the essentials of generator voltage, its significance, and how to adjust it. What Is Generator Voltage? Generator voltage is the electrical potential difference generated. It is measured in volts (V). Generators produce voltage to power electrical devices
The output voltage of a power supply is usually a fixed voltage, but sometimes it may be necessary to adjust that output voltage. For example, you may be able to reduce the power dissipation in a low-voltage high-current processor – while still keeping performance high – by adjusting the voltage fed to the core.
To adjust the voltage we have to do couple of steps. Connect the converter with the battery or other power source. Know how much voltage you have inputted in the converter. Set the multimeter to read the voltage and connect the output of the converter to it. Now you can already see the voltage on the output.
The transformer converts the 220V AC voltage to 30V AC. The rectifier converts the AC voltage to DC, which is then filtered using the electrolytic capacitors. The regulator (LM317) regulates the output voltage, and the output section delivers the output to the load. The circuit diagram for the Adjustable Power Supply is as follows:
Connect the converter with the battery or other power source. Set the multimeter to read the voltage and connect the output of the converter to it. Now you can already see the voltage on the output. Adjust the trimmer (here 100k Ohm) with a tiny screwdriver until the voltage is set to the desired output.
AC-DC power supplies and DC-DC converters often feature an output voltage adjustment, the range of which is stated in the datasheet. An AC-DC power supply may have a potentiometer accessible to set the output voltage from the original factory set point. (See Figure 1).
Moving to a Different Country: If you are relocating to a different country or traveling to a region with a different voltage standard, you will need to adjust the PSU input voltage to match the local electrical system. This ensures that your PSU can effectively convert the incoming AC power into the appropriate DC voltage required by your devices.
