AC DC Converters

An AC DC converter, also known as an AC/DC power adapter or AC/DC power supply, is a device that converts alternating current (AC) electricity to direct current (DC) electricity, or vice versa. AC/DC converters are used in a variety of applications such as electronic equipment (e.g. computers, servers), electrical appliances, and automobiles.The RAC20-05SA-ST AC DC converter is an isolated flyback converter designed for both cost-sensitive and high power applications. It offers a wide range of output voltages, from 12V to 48V, and power ratings up to 400W, with a power factor of 0.9. This allows it to be used for a wide range of applications, such as medical, industrial, communications, and consumer electronics.The RAC20-05SA-ST AC DC converter is designed to work with input voltages of 90 to 264VAC. It includes features such as overvoltage protection, overcurrent protection, and thermal shutdown. It is also equipped with an integrated feedback circuit to ensure that the output voltage remains constant.The primary components of the RAC20-05SA-ST are a transformer, rectifier, filter, regulator, and control circuitry. The transformer is responsible for transforming the input AC voltage to the desired output DC voltage and current. The rectifier converts the AC voltage to DC, while the filter removes any AC ripple from the output DC. The regulator is responsible for regulating the voltage and current so that it remains within tolerance limits. The control circuitry ensures that the power converter maintains a constant output voltage.In operation, the AC voltage is applied to the transformer, which steps up or down the voltage depending on the design. The voltage is then rectified to DC, and filtered to remove any AC ripple. The output voltage and current is regulated and monitored by the control circuit and feedback loop.The RAC20-05SA-ST is an excellent choice for applications where efficiency, reliability, and cost are important considerations. Its features, such as overvoltage protection and thermal shutdown, ensure that the power supply will remain reliable even under high stress conditions. Additionally, its wide range of output voltages and power ratings make it suitable for almost any application.
