How to use Voltage Regulators in a Circuit

Before we can hook up the circuit, let's first go over the pinout diagram of the voltage regulator, which is vital for hooking up the circuit. A voltage regulator is a 3-terminal device. Pin 1 is the Input Pin. The output voltage of whatever voltage source you want to regulate down (whether it's a transformer, battery, etc.) is fed into this pin. Oct 23,  · You will have to connect the two smaller wires to the alternator. The alternator usually has markings on it that say F and R. Connect F to where it says 1 on the regulator and R to where it says 2. Sometimes both the alternator and regulator markings say 1 and 2 or the regulator says F and R instead of the alternator.

A generator voltage regulator is needed to maintain a constant voltage within an AC or DC generator. While functioning, the engine within a generator works at different speeds according to the output that needs to be produced.

An over-worked engine could heat up and produce surges that can be detrimental to the generator. A voltage regulator is mostly used within automobiles to keep the battery from overcharging and malfunctioning. Check if your generator is functioning prior to installing the regulator.

Also, check the condition of the battery since it is an integral part of the system. Wiring between a generator, regulator, and battery is often prone to corrosion which can be removed with fine sandpaper. Before you remove any wires from their connection, tag them so that you can reconnect them. The generator has to be polarized before testing the regulator. Remove the battery after this step. Although some manuals state that the regulator needs to be polarized it actually just means the generator since regulators are not polarity sensitive.

Make sure that the regulator you use is suitable for the generator. The amount of voltage that your generator produces should fall into the range that the regulator can control. A popular range for a regulator is from 6 to 12 volts. Most regulators have the amperage and voltage marked on them for easy identification.

Do not assume that the higher the voltage indicated on the regulator, the better it is for your generator and battery. If you have an internal regulator, it implies that your regulator is mounted within the alternator and it cannot be removed or replaced.

If the regulator malfunctions, you will need to reinstall an entire alternator. Although most alternators come with an in-built regulator, some do have an external regulator. The ground terminal of the battery how to hook up a voltage regulator to be disconnected before working with the generator or the regulator.

The regulator will have three wires. You will have to connect the two smaller wires to the alternator. The alternator usually has markings on it that say F and R. Connect F to where it says 1 on the regulator and R to where it says 2. Sometimes what is tally marks in kindergarten the alternator and regulator markings say 1 and 2 or the regulator says F and R instead of the alternator.

Simply remember the respective connections. Connect the big wire to the battery. Make sure the wiring in all circumstances is done accurately since any misconnection will damage your regulator and generator. There are only three main wires that need to be taken care of within this system, the circuit breaker, current regulator, and the voltage regulator.

Introduction: Wiring an Adjustable Voltage Regulator

Jan 31,  · lovedatingstory.com this video i show how to connect a (sorry sometimes i say , i mean ) to get a 5 volts output form a 7 volt. Wiring an Adjustable Voltage Regulator Step 1: Parts List. Step 2: Step by Step Wiring. This is literally step by step, so there is probably a lot of redundancy, I wanted to make Step 3. Step 3. insert the voltage regulator next to the other end of the diode. Voltage regulators are also Step. Most voltage regulators have 3 pins: Input – This is the input voltage from the original source. For example a battery, or power supply. You feed the output of that device into the input of the regulator. The input should always be as clean as possible, and should .

Voltage regulators are designed to maintain and stabilise voltage levels. Regulators are found in most electronic devices, and can be used to step-down and control voltage outputs from a high voltage source, dissipating excess energy as heat.

This is great for applications where you need multiple discrete voltages for different devices within a single circuit, as you can use voltage regulators to step-down from a single higher output source! Input — This is the input voltage from the original source. For example a battery, or power supply.

You feed the output of that device into the input of the regulator. The input should always be as clean as possible, and should always be larger than the required output voltage. Most voltage regulators have a minimum specified input voltage, so make sure you adhere to this or the output may be lower than expected.

Ground — A common ground is required between the input and the output voltages. This should connect to the ground in the circuit, and is required for the regulator to function. How voltage regulators work is a subject in itself , so we won't go through it in detail here.

Suffice to say voltage regulators are essentially voltage dissipators that convert excess voltage into heat. A larger input voltage will result in a hotter voltage regulator as it works harder to get rid of that excess voltage, so users should be aware of this! Your wall socket outputs AC, whereas most appliances are DC.

If your regulator is situated more than 25cm 10 inches away from the power supply you'll need to add capacitors to the input 0. Voltage regulators work most efficiently when a clean DC signal is fed into it, and these bypass capacitor helps to reduce any AC ripple. Essentially, they act to short the AC noise of the voltage signal to ground, and filter only the DC voltage into the regulator. These two capacitors are not necessarily required, and can be omitted if you aren't too concerned with how much line noise there is e.

However, if you're building something like a mobile phone charger, or using the output for logic assessment, you'll want a nice clean DC line, so we would recommend including the capacitors!

The 0. The second capacitor, the 0. GND in this circuit is simply the negative side of this 12V source. The first 0. We can use to power any 5V devices, in this case an LED but you can attach any 5V device at this point! Create your account Lost password? First name. Last name. Your cart is empty.

Most voltage regulators have a minimum specified input voltage, so make sure you adhere to this or the output may be lower than expected Ground — A common ground is required between the input and the output voltages.

Output — The output pin spits out the regulated voltage. How do I use voltage regulators in a circuit? Excess voltage is dissipated as heat by the regulator, so take care when designing and using circuits. If it feels too hot it probably is too hot! Previous article Next article. Popular Tutorials.
