AC DC Desktop, Wall Adapters

The CENB1010A0903B01 is an AC/DC desktop and wall adapter designed specifically for providing power to laptops, security cameras, and kiosks. It is manufactured adhering to the International Electrotechnical Commission’s (IEC) standards and has a rated input of 100-240V, 50/60Hz, 1A maximum, and a rated output of 12V/3A, 33.8W max. This adapter is available with a 3-pin right angle plug and is supplied with an integrated mains lead, so can be used anywhere in the world where such plugs are present.

Application Field

The CENB1010A0903B01 can be used to power laptops, which require an input power rating of 12V/3A, 33.8W max. This adapter is suitable for powering CCTV security cameras, as well as for powering kiosks in shopping centers or airports. It is especially suitable for such devices due to its slim and compact design, which makes it easy to install in even the most tight or restricted spaces.

Working Principle

The CENB1010A0903B01 utilizes a switched-mode power supply (SMPS) topology to provide a regulated output of 12V/3A, 33.8W max. This adapter works by using a rectifier to convert the AC mains input voltage into a DC voltage. This DC voltage is then passed through an inductor to filter it and to reduce its size and weight. This filtered DC is then passed through an inverter, which is a high-frequency oscillator that uses MOSFET transistors to convert the DC voltage into AC. The AC voltage is then passed through a transformer and rectified again to provide the required output voltage of 12V/3A, 33.8W max. The output is regulated by a feedback loop such that any fluctuations in the input voltage will not affect the output.
