What Does Dc 9V Mean?

it changes the Alternating Current from your wall into 9 Volts of Direct Current.

What is a DC 9V adapter?

High quality 9v Power Supply, Built for Australian Standards
The AVE PSU-9V1A is a durable replacement power supply that delivers a 9V, 1A direct current (DC) output. Perfect for a wide range of electronic devices including compact effects lasers, DJ controllers, mixers, and more.

Are all DC 9V Chargers the same?

– Yes, they are likely interchangeable even though voltage is not the same. This is because the voltage difference is within specs, and I am GUESSING you could go even higher or lower in voltage.

Can I use a 12V power supply on a 9V?

If you have a 12V adapter, you might wonder whether you can use it to power your 9V guitar pedals. In most cases, you cannot use a 12V adapter to power a 9V guitar pedal. Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it.

What does 9V 300mA mean?

This is a linear adapter meaning that there is no voltage regulation, so with no load it outputs 15.6 volts and by the time it is loaded with 300 mA, the voltage is very close to 9 volts.

Can I use a 20V charger on a 19.5 V laptop?

Technically yes, but the prudent thing to do is find an OEM charger. Sure, 19.5 is very close to 20V and the 19.5V power supply can easily handle the 4.5A max of the lap top. Normally any device has a voltage range, not a tight fixed voltage requirement.

Can I use 500mA instead of 300mA?

Since 300mA is less than 500mA you should be fine. It will work, as long as the voltage is correct. The power adapter’s nominal power is 500mA so it will work at a lower cycle (60%) than its full power. It will work just fine.

What are DC adapters used for?

Direct Current Adaptors
A DC adaptor differs from an AC adaptor in that the DC adaptor converts AC electricity into DC electricity. For example, a 12 V DC adaptor sold in the United States will convert 120 V AC at 60 Hz into 12 V DC. Like its AC counterpart, a DC adaptor is also rated for maximum power output in watts.

What uses 9V power supply?

A lot of things use those small 9V batteries. Smoke detectors, some transistor radios (not so much any more), lots of handheld test equipment, electronic toys, etc. More and more things that in the past typically used 9V batteries are being designed to run from one to four AA or AAA cells.

Can I use 5v adapter for 9V?

No! It might work for few minutes, but eventually the voltage drop on the internal regulator will cause the circuit to overheat and burn.

Can I use 12V 1A for 9V 1A?

Yes you can. Just add a 12V, 1A regulator like a LM 7812 in series.

Can I use 500mA instead of 100mA?

For example, putting a 500mA pedal on a 100mA power tap would cause it to act erratically and probably shut down — it might even damage the pedal. Conversely, sending more milliamps than needed to a pedal is fine. Putting a pedal that draws 20mA on that same 100mA tap is no problem.

Can I use 500mA instead of 200mA?

If your adapter is 12V, 500mA, transformer based power supply (big, heavy in weight – around 0.5kg, not used generally these days) then it’ll draw only 50~200mA current from source (Source & Load Power will match).

Can I use 1000ma instead of 500mA?

If the device requests 500ma and the power supply can handle up to 1000ma, it’s fine. The device will only draw what it needs and no more. If the device demands more ma than the power supply can deliver, it will force the power supply to deliver it anyway thus frying the power supply.

Can I use 19V 3.42 A?

Q: Can we use 19V 3.42A charger in other Laptop which supports 19V 4.74A charger ? It should be okay. It is not a good idea to use a charger with a different voltage rating as this may cause damage to the laptop, or it may not supply any charge at all if the voltage is low.

Can I use 20V for 19V?

You can also see inside of your 20V power supply if there is a trimming pot for output voltage. Some power supplies have them. With a Volt meter you can adjust the voltage to read 19V, but most likely you will not need it. If it works, you are fine.

Can I use 19V instead of 20V?

Yes: technically it can be used, but you need a higher amount of power (watt). if the adapter is 19V 6A, it might start the PC but you will have strange side effects.

Will any 9v adapter work?

any 9v with the correct polarity (- inside +on the outside i think) that supplies enough amperes (250 milliamperes minimumi think) will work fine. As long as the voltage matches up, 9v DC pedal with a 9v DC power supply, you will be fine.

What does 300mA mean?

mA stands for milliamps and mAH stands for milli amp hours. So 300mA means 300 milliamperes of current is passing through the circuit whereas 600mAh means 600 milliamps of current passes in one hour. Normally electronics will be rated in mAh rather than just milliamperes.

Can I use higher mA adapter?

Can I use an AC adapter with higher amps? As long as the voltage matches that expected by the connected device, then yes, you can use an AC adapter capable of providing higher amps.

Can I use 5V instead of 3V?

There is not such thing (or there should be no such thing) as a 3V USB anything… USB is 5V, and always will be. It is a standard that all devices must comply with. This means that you should not be able to find an AC adaptor to 3V with USB, If you do find it, don’t buy it.
