AC DC Desktop, Wall Adapters

The ME20A1203B01 is a high current, high voltage AC/DC desktop and wall adapter. It is a widely used, increasingly popular DC solution, for commercial, industrial and domestic applications. The ME20A1203B01 is designed to meet the needs of both light and heavy load operations, with an output of 12 Watts DC at 12 Volts.

The circuit design of the ME20A1203B01 is implemented with a full-wave bridge rectifier, with an integrated voltage regulator IC. The bridge rectifier converts AC into DC, and is regulated by the voltage regulator IC.

The main components of the device are the input filter, transformer, bridge rectifier and output filter. The input side requires an AC input ranging between 85~265Vac and the output side provides the DC output of 12V/12W DC. The input filter reduces high frequency noise and other interference from the AC line.

The transformer is used to step-down the incoming AC to the desired voltage level. It is also used to provide isolation between the input and output. The bridge rectifier is used to convert the AC voltage to DC voltage. The rectified DC is then filtered and fed to the voltage regulator IC, where it is regulated to the required output voltage and current through SMD resistors and capacitors.

The output filter is used to reduce the output voltage ripple and prevent high frequency noise from returning to the AC line. The output filter components are designed to ensure a stable output voltage at all times, while the power output of the device is capable of delivering up to 12V/12W DC.

The ME20A1203B01 AC/DC desktop and wall adapter is ideal for applications such as security systems, medical equipment, electronic hobby projects, industrial controls, power supply for communications equipment, point of sale systems, lighting, and motor control. It is also suitable for low voltage, low current computer applications such as small servers, battery charger systems, portable monitors and devices, alarm systems, and power tools.
