What is AC DC plug?
In a nutshell, an AC-DC power supply converts one type of electricity (AC – “alternating current” into DC – “direct current.” Each day, most people will undoubtedly use electrical devices that require both types of electricity. For example, your car requires a 12v DC electricity supply to operate.
Can I use an AC plug for DC?
In many instances, yes. The central function of AC adapters is the conversion of mains current from AC to DC for electronic devices with a rechargeable battery.
What can you plug into a DC outlet?
In the past, 12V DC adapters used a variety of incompatible plugs in addition to a range of voltage and amperage outputs….Common devices that can use 12V USB adapters include:
- Cellphones.
- Tablets.
- GPS units.
- FM broadcasters.
- Bluetooth hands-free devices.
How do I know if my power supply is AC or DC?
One way to determine if you have an AC-DC power supply or a DC-DC model is to look at the device itself. Often, the input and output information will appear somewhere on the surface. If the input is AC, you have an AC-DC power supply, and you have a DC-DC model if the input and output both are DC.
What happens if I plug AC into DC?
most likely it will short out the DC and something will melt or fuse. If you have a modern SMPS switchmode AC adapter then it will likely be coupled directly into a rectifier and filter. Now a lot depends on the DC voltage source you have, its voltage primarily but also how much current it can deliver.
What is the difference between 12V DC and 12V AC?
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.
What is DC power cord?
A DC power supply cord is used to connect a DC power supply to a device that uses DC power. DC power supply cords are available in different lengths and can have either two or three prongs. A DC power extension cord is used to extend the length of a standard DC power cable.
What is an AC adapter plug?
An AC adapter, AC/DC adapter, or AC/DC converter is a type of external power supply, often enclosed in a case similar to an AC plug. Other common names include plug pack, plug-in adapter, adapter block, domestic mains adapter, line power adapter, wall wart, power brick, and power adapter.
What is an AC adapter Charger?
Alternatively known as an AC/DC adapter, AC converter or charger, an AC adapter is an external power supply used with devices that run on batteries or have no other power source.
What is a power plug adapter?
A power supply for electronic devices. Also called an “AC adapter” or “charger,” power adapters plug into a wall outlet and convert AC to a single DC voltage . Computers use multiple DC voltages, and the power adapter is the external part of the power supply for a laptop. The additional DC voltages are created by internal circuits.
