The AC DC switching adapter 100-240V 50/60Hz is a universal power switch machine, which has been designed to cater to the needs of many electronic applications. It transforms alternating current (AC), coming out from a wall socket, into direct current (DC) that is suitable for electronic devices. It supports input voltages within a wide range, 100-240V, which means it can work in different electrical systems around the world. What's more, being compatible with both 50 and 60 Hz frequencies makes it possible for this adapter to go anywhere without worry on region-specific constraints such as voltage regulations or explicit electrotechnical requirements. It provides such vital functions as voltage transformation, regulation, and isolation - functions which are vital to protect electronic devices from power surges and electrical noise. Technological features include a compact design, high efficiency, low energy consumption and built-in over-voltage, over-current, and short-circuit protection. This adapter is suitable for usage with laptops, smart phones, tablet PCs and other portable electronic devices.
