# What does 12v DC 500ma mean?

## What does 12v DC 500ma mean?

Very simply, that you have a power supply output that provides 12 volts of DC, at a of current UP TO 500 mA. You can use that supply with any device that requires a 12V input, and which does not require more than 500 mA of current.

### Can I power 12v AC with 12v DC?

As long as the voltage of the “DC Appliance” is not less than the 12 Volt adapter then it will either work or won’t, all in all it’s a bad idea to experiment, actually it’s a bad idea just to even think about doing it, unless you know about what you are about to do, don’t.

What is a 12v DC adapter?

The 12 Volt Power Adapter, also known as a “Brick”, “Desk Wart” and “Floor” supply, provide a regulated 12 Volts DC output. A 12 Volt Adapter Power Supply is enclosed in a plastic protective case that comes with either an attached AC cord, or a mating socket for one of the 3 common IEC cordsets.

What is 500mA electricity?

Milliampere to Ampere Conversion Table

Milliamperes Amperes
400 mA 0.4 A
500 mA 0.5 A
600 mA 0.6 A
700 mA 0.7 A

## Can I use a 12V power supply on a 16v?

It just has to supply the requirement. It could have the capability of supplying much, much more current, but it only what is needed will be supplied. No you can’t.

### Is 12V AC and 12V DC the same?

12V DC is safer than 12V AC. Body resistance decreased when the 12V AC still may cause the dead, 12V DC will not be in 100%. However, the hazard degree of electric shock to the human body mainly depends on the size of the current passing through the human body and the length of the energization time.

Is 12 volt AC the same as 12 volt DC?

No 12 Volt DC and 12 Volt AC are not the same thing. They are extremely different given the extremely different properties of AC and DC. Even though the voltage is 10 Volts in both cases, the properties of 10 Volts DC and 10 Volts AC will be very very different.

What uses a 12V DC power supply?

Devices that are often compatible with proprietary 12V DC adapters include: Cellphones. Laptop computers. GPS units.

## What is 12V DC output?

12V power supply is one of the most common power supplies in use at present. In general, a 12VDC output is obtained from a 100VAC-277VAC input using a combination of transformers,12V power supplies can be of two types: 12V constant power supplies, and 12V unconstant power supplies.
