RS Pro Plug-in AC-DC adapter with Interchangeable Output Connectors, Europlug

From RS Pro a high quality and versatile plug-in AC-DC adapter for converting AC mains current into DC voltage for a wide range of DC applications. This adapter has a 2 pin europlug for use with european mains power and features 6 selectable output voltages from 3 V DC to 12 V DC. These voltages are selected by turning a recessed rotary switch on the back of the adapter. This AC adapter is supplied with 8 different output connectors consisting of jack plugs and hollow barrel connectors that allow it to be used with a wide range of products.

What is a Plug-in AC-DC Adapter?

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 AC (alternating) current. This is where an adapter is required to convert the AC current into a usable DC current.

How Does an AC-DC Adapter Work?

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 is terminated by a DC power cable on the end of which you simply plug in one of the 8 DC connectors that is appropriate for your equipment. This DC connector is then plugged into the device which is being supplied. 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

Where are AC DC Adapters Used?

AC DC power adapters are used to power small or portable electronic devices. This AC adapter is ideal for use with the following applications:

Computer peripherals Networking equipment Portable equipment Tablets and Laptops Smartphones Instrumentation Telecommunications equipment
