Increase primary voltage but decraease amerage - eg double voltage and half amperage. This will double your secondary voltage. "Transformed" voltage is easy to understand by following this simple math rule.
secondary voltage divided by primary voltage = no of turns on secondary and no of turns on primary.
eg;
240v \ 12v = 20 (factor)
this means the secondary winding is 20x the primary winding. Basically thats all I know Stick to this rule for step up & step down tranforming & you'll be sweet.
What else can I help you with?
How can I convert a DC adapter operated device into one that uses a battery?
A: A DC adapter is basically like a battery except it is conditioned from an AC source. To change over measure the voltage when fully operational then switch to battery that have the same voltage as the adapter. the only concern should be the power required
What is the difference between transformers and adapters?
A transformer is a component that changes AC current from one voltage to another. A transformer consists of two coils, one connected to the input, and one connected to the output. A transformer can convert voltage up or down, depending on the number of windings on the coil. An adapter MAY include a transformer to change the voltage, but an adapter usually changes the voltage AND converts from AC to DC as well, and may have a regulator that locks the voltage to prevent a surge and other components that prevent what is called "ripple".
What AC actually means in AC adapter?
Alternating Current ... like in most households.The adapter is either converting DC to AC or vice versa.
Can you use a 7.5V Ac Adapter to charge a 6V battery?
No, it will overcharge the battery and overtime destroy it.
Is DC voltage and average voltage same?
no, dc volatage is a type of current direct current, ac is alternating current, average voltage could be any type of voltage ac or dc that maintains a constant rangeAnswerNo. A DC voltage is exactly equivalent to an AC rms-voltage. So, for example, 100 V (DC) is exactly equivalent to 100 V (AC rms). The average value of an AC waveform is zero.
Ac Adapter is it ok to use higher voltage?
On both the primary side and the secondary side the answer is no. It's OK if the voltage is within 10% of your original AC Adapter.
Can you use a 12v halogen bulb with a 6v AC adapter - wattage is the same?
No, you cannot use a 12v halogen bulb with a 6v AC adapter. The voltage of the bulb must match the voltage of the adapter for them to work properly. Using a higher voltage bulb with a lower voltage adapter can cause the bulb to burn out or potentially damage the adapter.
Who to increase torque of ac motors?
ac voltage
What is the voltage adapter for use in European countries?
Step down transformer from 220 volts AC to 110volts AC
What if I Used wrong ac adapter in electronic device?
If the AC adapter gives too little voltage, the electronic device will probably not work. If it gives too high a voltage, you will probably burn out the electronic device, which will have to be replaced or rewired. If the AC adapter is too weak (provides less milli-amperes than the device needs), the AC adapter can burn out. In summary, you need to check: (a) that the adapter should have the correct voltage, and (b) that it provides the required amount of milliamperes (or more) for the device.
Can a 12 volt 0.5 amp ac adapter substituted with a 7.5 volt 1 amp adapter?
No, it is not recommended to substitute a 12 volt 0.5 amp AC adapter with a 7.5 volt 1 amp adapter. The voltage and amperage ratings need to match the requirements of the device you are powering. Using a lower voltage adapter may not provide enough power, and using a higher voltage adapter can potentially damage the device.
Can you use a 13v 2.77 amp ac adapter in place of a 12v 3.0 amp ac adapter?
It is not recommended to use a higher voltage adapter than what is specified for your device. Using a 13V adapter instead of a 12V adapter may damage your device due to overvoltage. It is best to use the adapter with the exact voltage and current specifications that are recommended by the manufacturer.
Can you use 5v ac adapter instead of 4.5v ac adapter?
Yes the voltage is close enough to work. What you have to be cautious about is the milliamp output of the adapter. Make sure that the output of the adapter is higher than the device that plugs into it.
Is the Nintendo Wii dual voltage?
The original AC adapter that comes with the Nintendo Wii is not dual voltage. However, you can purchase a 3rd party 110-220 volt ac adapter specifically for the Wii. Here is a link to a merchant selling such an adapter. http://sky2k.com/shop/nintendo-wii-universal-power-adapter-100v220v-p-279.html
Ac adapter is it ok to use lower voltage 19v 4.74a ac adapter has died. Can I use a spare I have in the mean time it's output is 12v and 5a?
not unless you want to fry your electronics
Does DC adapter mean the device converts DC to ac or ac to DC?
An AC adapter adapts the device that one wants to power up to the AC line. That means it converts the AC line voltage to something that can be used by the device in question. An AC adapter converts AC to DC. (In contrast, a device that runs off DC and makes AC out of it is called an inverter. An example of an inverter is the device that plugs into a vehicle's cigarette lighter and has an outlet on the other end that will permit someone to plug something like a kitchen blender into it. Great for tailgating! Don't run your vehicle's battery down....) There are times when an AC adapter is the little plug-in-the-wall thingie that converts the AC line voltage to some lesser value of AC. There are a few devices out there (usually older ones) that used their AC adapters to step down the wall voltage (115 volts AC) to 24 volts AC, 18 volts AC, 9 volts AC, or anything like that. Some new sprinkler control timers use an adapter that is an AC -to-AC step down converter. By looking at the information on the adapter, the user can see what the primary voltage is (and it's almost invariably 115 volts AC or 120 volts AC - same, same for this application) and what the secondary voltage is. As stated, the secondary is almost always DC, and if it is, the polarity is almost always indicated as well. That's so a user can tell if that little round connector has positive on the inside and negative on the outside or the other way round. (It makes a lot of difference to the device on which it is used, as one might guess.)
When ac convert in dc then voltage will increase or decrease?
You can make it so it does either increase or decrease. The limiting factor is that power out cannot exceed power in. So going to a higher voltage will limit current and going to a lower voltage will increase current available. A2 Because AC is continuously changing in a sinusoidal waveform, it is hard to determine the exact voltage. It is usually called by it's RMS value (Root Mean Squared). The result is that when you fully rectify an AC voltage, the DC voltage is actually HIGHER than the RMS AC voltage.
