# How do you convert 230 volts to 12 volt system?

With a Step Down transformer. But you will probably have a hard time finding a 240 volt unit. 120 volts units are readily available. It depends on how big of a transformer th…at you are looking for. There are many control transformers in the 50 to 500 VA range that have dual primary and dual secondary. The primary side can be connected to 240 volt or 120 volt and the secondary can be connected for either 12 or 24 volts.

# How do you convert 12 volts to 3 volts with resistors?

Calculate the impedence of your 3V circuit in ohms. Figure the voltage you want to drop. In this case, you need to lose 9V. This is three times the voltage you …are supplying, so the resistor should have three times the resistence of your 3V circuit. If your circuit has 100 ohms of resistence (impedence), then you would connect a 300 ohm resistor in series with your circuit.

# How do you convert a 12 volts solenoid into 24 volts solenoid?

If you really wanted to do that you'd have to pull the winding off the coil and replace it with another winding. It'd be far easier simply to replace the 12V unit with a 24V u…nit.

# How do you convert 12 volts to 3 volts?

Stepping down AC voltage To step down 12 VAC to 3 VAC, you could use a step-down transformer with a winding ratio of 4:1 between primary and secondary. Stepping Down DC Vo…ltage There are a number of ways one can step down 12 VDC to 3 VDC, but they basically fall into three categories: Unregulated voltage dividers Linear voltage regulators Switching voltage regulators Voltage Dividers A voltage divider is two or more resistors connected in series with a power source, which causes the voltage to be divided between them. For example, if you were to connect a 30 ohm and a 10 ohm resistor in series across a 12 volt supply, the voltage across the two resistors would be 9 volts and 3 volts, respectively: __________________VT = 12 V _____________________ |...................R1......................................... R2........................| +12V----| 30 ohm |--------+3V----------| 10 ohm |-------Ground |...................................... |................................................... | --------------VR1 = 9V-------------------------VR2 = 3V-------------- RT = R1 + R2 VR1 = VT R1 / RT VR2 = VT R2 / RT Note that trying to draw power from the point between those resistors would quickly cause the voltage to drop because of the parallel resistance of the load. Instead, substitute the device as one of the resistors. So, to get 3V to your device, you could measure the resistance of the device, then pick a resistor that is 3 times the resistance of the device, and connect the device to 12V in series with that resistor. The resistor will have to have a wattage rating of at least 3 times the power used by the device (or 9 watts divided by the resistance of the device), to keep from overheating. Also, If you are using batteries for power, make sure that the resistors you connect are of a high value in the order of kiloohms or else the resistor divider network could drain your power source. The problem with this approach is that if the input voltage (12V) changes, or the resistance of the device fluctuates, the voltage to the device will fluctuate. Basically I would only use this method for simple resistive loads such as light bulbs. Linear Voltage Regulator A linear voltage regulator is a circuit that acts like a voltage divider, but automatically changes resistance to maintain a constant output voltage regardless of change in the current drawn from its output, or variations in the input voltage. While the circuit itself has a bit of complexity, integrated circuits that perform this function are commonplace and inexpensive. One the cheapest and most readily available is the LM317T ($2.29 at Radio Shack) regulators, which accepts an input of up to 40V and has an output voltage of 1.2V to 37V, determined by a pair of resistors attached to the regulator. This regulator can provide up to 1.5 amps of output, more with the addition of external transistors. I've posted a URL to the datasheet for this regulator in the Links section. Linear shunt regulator A shunt regulator made from a resistor and a zener diode is another type of linear regulator. Connect a resistor from 12V to the cathode of a 3V zener diode, and the anode to ground, then connect the load from the cathode to ground. The zener diode will draw current as needed to hold the load voltage near 3V. The output voltage will vary with load current, although not as much as a voltage divider. It will also vary with temperature. The zener diode and resistor must be sized correctly to handle the currents involved. Switching Voltage Regulator One of the disadvantages of linear regulators is that they are very inefficient, especially when drop between input and output voltages is large, because the extra voltage has to be dissipated away as heat. In the case of regulating 12V down to 3V, you are basically throwing away 3/4 of the power being used, meaning an efficiency of less than 25%. In some applications this might be acceptable, for example in an automotive application where plenty of current at 12V is readily available. In other applications such as battery powered devices, such a waste would be a bad thing. Switching voltage regulators work on a much different principle, switching the power on and off at a high rate of speed to regulate the output voltage (see the URL for DC-to-DC Converters in links for a more detailed explanation). They offer efficiencies of up to 95%, and can even output higher current or voltage than the input. They are more expensive than linear regulators, but offer more performance per buck - for example, for $9.25US through Digi-Key the LT1074 (see link) can provide up to 10 amps of output, and accept input voltages up to 60V. Actualy two types passive and active. No matter what names to add to that.

# How do you convert 12 volts to 5 volts DC?

Voltage divider is ok if your load is only few milliamps. As more load you have the more power (or heat) the series resistor has to dissipate and of course there will be volta…ge drop on the resistor. This means that it will be difficult to regulate the output. 2 options: 1. Use linear voltage regulator such as LM340T-5.0 or 7805. The most common version is the 1 amp version but there is a 3 amp and a 0.5 amp version. Because this is linear, heat must be dissipated. You need large heatsink if you have high load. 2. Use switch mode regulator such as LM2677. Because it is switch-mode the efficiency is close to 100, thus little heat si dissipated even at full load. Most of the time no heatsink is required and the whole circuit will fit inside the cigar lighter plug.

# Do you replace the coil from a 6 volt to a 12 volt when converting from 6 volt to a 12 volt system?

Yes. Since the coil is run at full voltage when starting 12 volts may be too much for a 6 volt ignition coil. It would be at about 8 volts when running. There is a starting re…sistor.

# How do you convert 12 volt dc to 12 volt ac?

# Is a 2007 Honda Rebel a 6 volt or a 12 volt system?

I believe this is a 12 volt system. an easy way to check this is a multi-meter. I would recommend purchasing this tool because it always comes in handy and is worth the money …when working with electrical systems.

# How do you convert 24volts to 12 volts?

If you want to convert 24v AC into 12v Ac, it's simple. Just get a transformer to convert 24 volts into 12 volts. This is called a stepdown transformer. If you want to… convert 24v DC into 12v DC, it's more complicated. First you have to change the 24v DC into 24v AC by a switching converter that changes DC into AC. Then you would use a stepdown transformer as in the former example. Once the 24v AC is converted to 12v AC, then you use a rectifier bridge to change the 12v AC into 12v DC.

# How do you convert 5 volts to 12 volts?

You should use ULN2003 or LM398 driver for it

# Can you convert a 24 volt battery charger to 12 volts?

You can try to charge two 12 V batteries at the same time . Using a series circuit, place both batteries next one to another, and connect the negative pole of one of them to t…he positive pole of the other. Then use the remained poles to connect to the charger. The only other way possible, is to change the transformer, but this would be as expensive as buying another charger.

# How can you convert 240 Volts to 12 Volts?

You would need a transformer specially made to do this. Of course, this transformer would need a rectifier, as I am assuming that you need 12 volts DC.
