RS PRO, 1 A

From RS Pro cost-effective and highly reliable plug-in AC-DC adapters for converting AC (alternating) mains current into a 5 V dc voltage using a USB connector. These power adapters feature 4 interchangeable AC mains plug heads allowing the adapters to be used in the UK, Europe, USA and. Besides being used for serial digital data exchange the USB connector has now become a standard low power AC adapter for many portable devices.

Plug in AC-DC adapters are also known as AC Adaptors or AC-DC converters and are a type of external power supply. Some electrical appliances require power but lack the internal components to derive the required voltage and power from mains power. This is where an AC adapter is used to convert the AC current into DC voltage

The adapter consists of a power supply which is enclosed in a case similar to an AC plug, hence the term plug type, plug-in or plugtop power adapter. One end of the power supply contains a USB socket into which you connect one end of your USB cable, the other end of the cable is plugged into the USB port in your device. The power supply is plugged into the mains socket and the AC current is then converted by the adapter into a DC voltage that is fed into the appliance via the cable connection

The numerals I to VI are an International Efficiency Marking Protocol which allows manufacturers to designate the efficiency performance of a product. This performance is based on the measurement of the operating energy efficiency and no-load power consumption of power supplies tested at different load levels. The no-load power consumption refers to the amount of power that an external power supply draws even when the application is turned off or disconnected.
