The adaptor converts AC wall power to 9-volt DC for powering most instrument pedals and other 9-volt battery devices. The tip negative, sleeve positive power supply can handle 500mA to power even your most power hungry devices.

What uses a 9-volt 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.
What is a DC power supply?
A DC power supply is a type of power supply that gives direct current (DC) voltage to power a device. Because DC power supply is commonly used on an engineer’s or technician’s bench for a ton of power tests, they are also often called a “bench power supply.”
What is 9V DC battery?
The nine-volt battery, or 9-volt battery, is a common size of battery that was introduced for early transistor radios. It has a rectangular prism shape with rounded edges and a polarized snap connector at the top.
Are 9V batteries DC or AC?
There are two flavors of voltage: alternating current and direct current. Here is a quick look at the differences. The direct current voltage of batteries is what comes out. The 9V battery keeps the voltage constant until it dies.
Are all 9V power supplies 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.
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 do you use a DC power supply for?
The main job of an AC/DC power supply is to transform the alternating current (AC) into a stable direct current (DC) voltage, which can then be used to power different electrical devices. Alternating current is used to transport electric power all across the electric grid, from generators to end users.
What is DC example?
Examples of DC electronics include: Cell phones. The LilyPad-based D&D Dice Gauntlet. Flat-screen TVs (AC goes into the TV, which is converted to DC)
Where is DC power supply used?
DC power is widely used in low voltage applications such as charging batteries, automotive applications, aircraft applications and other low voltage, low current applications. All solar panels nowadays produce DC power.
Can I use a 9V DC adapter in place of 6 AA batteries?
Yes provided the adapter meets the current & voltage demands of the load.
What is a 9V battery called?
The alkaline variant of the 9V battery is also referred to as 6LR61 and 006P. Other industry names for the 9V battery can be Duracell MN1604, Rayovac A1604, Energizer 522, Varta 4922, MX2400, 1604A, Radio Battery, Smoke Alarm Battery, 9V Block, and Krona.
How much current can a 9V battery supply?
A standard 9V battery has about 400-600 mAh capacity. In the most basic terms, these batteries can supply about 500 milliamps for one hour before being “dead”.
How do I convert a 220V AC to 9V DC?
Basically a transformerless power supply is just a voltage divider network that takes the 220V AC as input and divides it down to Lower DC voltage that we want. The AC voltage need is rectified through a few diodes and regulated to a maximum voltage.
How do you convert DC to DC?
Practical electronic converters use switching techniques. Switched-mode DC-to-DC converters convert one DC voltage level to another, which may be higher or lower, by storing the input energy temporarily and then releasing that energy to the output at a different voltage.
Can I use 9V instead of D batteries?
Never, never, never mix capacities of batteries in series connections. It will not behave as you might expect and can cause serious problems. Mixing an alkaline 9V battery with a couple of D cells could cause the 9V battery cells (internal) to heat and spew out caustic liquid.
Why is DC used in batteries?
Direct current (DC) is an electric current that is uni-directional, so the flow of charge is always in the same direction. As opposed to alternating current, the direction and amperage of direct currents do not change. It is used in many household electronics and in all devices that use batteries.
Are batteries DC power?
All batteries, including the lithium-ion batteries powering everything from electric vehicles to drones to computers, operate with direct current (DC). A majority of appliances rely on AC, or alternating-current, power sources.
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.
Can I use an AC adapter for DC?
AC adapters use a diode rectifier circuit to ensure the electricity coming out is only DC. So if you were to connect it to DC, it will also still work and also doesn’t matter what polarity.
