AC to DC 12V 1.5A Power Adapter Supply, Plug UK 5.5mm x 2.1mm

Product Information

The load / laptop / whatever does NOT pull – it lets the current through; faster if the resistance is low, slower if it’s high.

Remember what the article said: the voltage remains constant, and the amperage is dependent on the device’s needs, regardless how many are connected. We and our partners use data for Personalised ads and content, ad and content measurement, audience insights and product development. The losses increase a the square of the current so a doubling in load will more than quadruple the I Plug a device expecting 110 volts into a 220-volt socket, and you’ll probably see sparks followed by darkness as the circuit breaker trips. This is one reason why getting the voltage correct on a power supply is so critical, because it can, in a sense, “push” too much electricity through a device and cause it to overheat or be damaged.To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. These popular electronic devices are used in a wide range of industrial, commercial, and domestic applications. A power supply is used to reduce mains or three phase electricity, often at 240 Vac or 440 Vac down to a voltage that is usable, such as 12 Vdc. Thinking of purchasing a 12 V ac adapter, well look no further, here at RS we offer a range of high-quality power supplies to suit your every need.

If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page. This means most can work worldwide with nothing more than an adapter to account for the physical plug differences — no voltage transformer needed. But I thoroughly agree with your working rules; get the voltage exactly right, and only substitute a higher current power pack where a lower current one used to be.USB wall chargers have to provide the same voltage (like the article said, it’s fixed), but some are capable of providing higher amperage for those devices that can use it. In practical terms, that means the amperage rating of a power supply or charger must match or exceed that required by the device it is connected to.

AC chargers are usually represented by a tilde (~), and pulsating DC chargers are indicated by a solid line over a dotted line, kind of like highway dividers where there’s no passing in one direction. Our range includes AC-DC power supply adapters and desktop computer power supply suitable for domestic applications, as well as bench power supplies, DIN Rail and panel mount power supplies and switch mode PSU. As long as the correct voltage is used, a device will draw only the amperage it needs, meaning there will not be “too many amps”. Because a) the voltage matches, and b) the amperage provided is greater than that needed, you can use a 5v-2A charger with a 5V-1A device.If the device expects the center connector to be positive and the outer ring to be negative, your power supply’s connector must match. The input voltage and amperage ratings are unrelated to the charger’s compatibility with your device. Power supplies are a crucial aspect of any electrical equipment, providing reliable power to machinery, computers or other technology devices. If an incorrect voltage is used — say a higher voltage than the device is rated to accept — then yes, too many amps may be drawn, and the device can be damaged. 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.
