AC/DC Converters are essential components of many power systems, typically found in control circuits and other electrical equipment. AC/DC converters take the alternating current (AC) coming from the input power source, such as a battery, and convert it into direct current (DC). This conversion process is particularly useful in critical, space-sensitive applications, where high power transfer efficiency is required. The RAC04-09SA is a small, compact, AC/DC converter module, ideal for incorporating into various types of power systems and industrial equipment.

The RAC04-09SA features an incredibly efficient high-voltage performance, with a maximum power conversion efficiency of up to 97%. This advanced AC/DC converter module is designed to handle both AC and DC power inputs, and its high efficiency allows for improved power transfer accuracy, providing stable and reliable power for the connected components. Additionally, the RAC04-09SA supports a wide input voltage range from 80 VAC to 264 VAC, and also features built-in surge protection capabilities up to 400V, giving greater flexibility and protection when using in applications that may have heavy surges.

The integrated power factor controller (PFC) chip featured on the RAC04-09SA ensures a high level of power factor, reducing negative power loss and improving overall conversion efficiency. In addition to the efficient power conversion, the RAC04-09SA also offers overload and short circuit protection, ensuring stable operation in the event of an overload or short circuit. The built-in temperature compensation controller also helps to maintain the output voltage and current stability.

In terms of operation, the RAC04-09SA AC/DC converter module is controlled by a specialized switching circuit, where an integrated voltage-controlled oscillator (VCO) is used to create the “pulse width modulation” (PWM) signal to control the switching power element. This PWM signal is then amplified and then transmitted to the switching element. When the PWM cycle is complete, the module will then switch off the power supply and reset itself before starting the next cycle. Overall, the RAC04-09SA is a small yet powerful AC/DC converter module which offers high conversion efficiency, excellent power factor performance, and a variety of protections for robust and reliable operation.
