AC-DC Desktop, Wall Adapters

The MENB1010A0951B01 is an AC-DC desktop, wall adapter. It is a device, which takes power from the alternating current (AC) power grid supply and converts it to direct current (DC) power for use in the most common electronic equipment. It is a combination of an AC-DC power supply/converter and a switch-mode power supply, both of which are used for a variety of applications.Their function is similar to that of the transformers which used to be used, with the difference that they do not require a physical link between the source and the output, as the AC and DC side are isolated, that is, they do not touch each other electrically.

MENB1010A0951B01 is a reliable and efficient AC-DC adapter, with a robust output power of up to 10A, and a wide voltage input range of 85-265V AC. This adapter is suitable for applications which require a stabilized voltage supply such as televisions, audiovisual equipment, DC motors, pumps, telecommunication systems, industrial electronic systems, and even medical equipment. This adapter is built with the highest quality components, and also features advanced safety features such as input and output short circuit protection, as well as a low-noise output for a smooth working environment.

Working Principle

The MENB1010A0951B01 AC-DC adapter is composed of two parts: an AC-DC power supply/converter and a switch-mode power supply. The AC-DC power supply/converter takes AC power from the mains, usually at 50-60Hz, and converts it to DC power, using a rectifier and a series of capacitors. This DC power is then fed into a switch-mode power supply, which converts it into the desired output voltage.

The switch-mode power supply works on the principle of “pulsed-width modulation” (PWM), where a series of high-speed semiconductor switches open and close in rapid succession to control the amount of energy sent to the capacitor. The number of times the switches operate depends on how many cycles the AC mains voltage passes through from its peak value to its valley value. This rapid switching between high and low provides a much better regulation of output voltage, allowing for the precise output voltage control that is required for most modern electronic devices.

The switch-mode power supply is also responsible for delivering the required amount of power to the load, as well as protecting it from various power anomalies, such as voltage surges or dips, and current overloads. The output of the switch-mode power supply is always DC, regardless of the input voltage, ensuring that the device itself is always functioning safely and efficiently.
