AC DC Converters: RAC15-12SA Application Field and Working Principle

RAC15-12SA is an adjustable AC/DC converter manufactured by Sunrise Automation. It is mainly suitable for AC input voltage (VAC) range of 150V- 305V and provide efficient DC voltage (VDC) output of 24-12V, with an output current of 2A-15A. This versatile AC-DC converter is built with a metal case and features an input frequency of 47-63Hz. RAC15-12SA is a wide input AC-DC converter and could be used in many applications, such as LEDs lamps, industry, medical devices, electronic equipment, and consumer electronics etc. It has much higher efficiency than the traditional transformers, as it includes technologies such as pulse width modulation (PWM) and constant current output to reduce the power consumption and size.The working principle of RAC15-12SA is to convert AC input voltage into DC voltage output. The AC input voltage is applied to primary power supply circuit and then it is rectified by diodes and filtered to generate regulated dc output. The output voltage is adjustable with an output voltage potentiometer according to the needs of the application. To keep the voltage steady, RAC15-12SA uses a feedback circuit. This circuit monitors the output voltage and rectifies any drift in the voltage. It is also featured with over voltage protection to protect the power supply from voltage spikes.A cooling fan is provided with RAC15-12SA AC-DC converter. It helps in keeping the device cool during operation such as over-voltage protection or overload protection. It effectively eliminates the heat from the built-in components and provides higher efficiency and reliable performance.In conclusion, RAC15-12SA AC-DC converter is a high performance and cost-effective solution for various applications. It features simple installation, good thermal performance, and high efficiency. The adjustable voltage feature allows it to be used in applications with varying input voltage. Therefore, it is an excellent choice for applications requiring adjustable DC voltage output that are reliable, efficient and cost-effective.
