AC-DC converters are devices that are capable of converting alternating current (AC) to direct current (DC). The RAC20-3.3SB is an AC-DC converter manufactured by Efore Power Solutions. This device is a 3-in-1 power converter, capable of providing output power of up to 3.3V DC. It is designed to be robust and efficient, with a wide working temperature range of -20 to +85°C and an average efficiency of more than 92%.

The RAC20-3.3SB is ideally suited for a wide range of applications, such as industrial, telecommunications, automation, metering, and control systems. It is also suitable for applications in which high efficiency, low noise, and reliability are key requirements. The device is capable of interfacing with different types of input voltage, such as 115/230V AC, and can be used in various modes such as constant current, constant voltage, and constant current/voltage. In addition, it has a wide output power range of 0.06 to 3.0W.

The RAC20-3.3SB utilizes a switch mode power conversion technology known as “full-bridge rectifier and buck-boost converter” to convert AC-to-DC. The device uses a transformer to convert the high voltage AC input to a low voltage AC. This AC voltage is then rectified by four fast-recovery Schottky diodes, creating a full-wave rectified DC voltage. This DC voltage is then filtered to provide a smooth DC output voltage.

The RAC20-3.3SB is also an adaptive switching converter, meaning it can recognize and rectify different AC input voltages. The device utilizes a phase-lock-loop (PLL) for this purpose, by comparing the rectified DC output to the incoming AC voltage, and automatically adjusting the output voltage. This PLL also helps to eliminate any noise, resulting in a stable, clean output voltage.

The RAC20-3.3SB has many advantages over traditional linear technology, including high efficiency, low noise, high power density, and a wide working temperature range. In addition, the device has automatic safety features, such as over-voltage protection and thermal protection, to ensure reliable and safe operation. These features make the RAC20-3.3SB an ideal power conversion solution for a variety of industrial, telecommunications, and other applications.
