AC DC Converters - RAC15-05DA-E-ST Application Field and Working Principle

The AC DC Converter RAC15-05DA-E-ST is an innovative power converter that has a wide range of applications in many industries, such as commercial, industrial, aerospace, telecom, medical, military, automotive, and instrumentation. The device is an AC-DC converter, a type of rectifier that converts alternating current (AC) into direct current (DC). This is important because so many of our electronic devices today require DC voltage from the wall. This product is designed to reduce the cost of power conversion and its impact on the environment.

The RAC15-05DA-E-ST features a high-efficiency ratio, low cost, small size and features an ultra-wide input voltage range from 85V to 375VAC. It features overvoltage, overcurrent, over temperature, and short circuit protection. Another beneficial feature of this product is its high surge power capability that allows for smoother operation when used in applications such as motors where high levels of starting currents are needed. It also features a low current ripple and low distortion input which offer excellent regulation over a wide input range.

Understanding how the device works requires an understanding of the underlying principles of AC-DC conversion. When AC current flows through the input of the converter, it passes through a full-bridge diode rectifier, which converts the AC current into DC current. The DC current is then taken through an EMI filter to reduce noise and then to a transformer, which increases the voltage and isolates it from the input. The voltage passes through a diode bridge which is connected to an inductor and capacitor that form a low-pass filter. This filter removes the high frequency components of the voltage, allowing it to remain as low frequency DC voltage. The output voltage is then regulated using a switching power regulator to maintain a steady voltage level.

The RAC15-05DA-E-ST device is primarily used in applications requiring power from AC mains that may have a wide input voltage range. This makes the device ideal for applications such as LED lighting, PLCs, medical e-devices, motor drives, industrial electronics, solar power components, and refrigerator & air conditioning systems. This device is also widely used in aircraft and electric vehicle applications due to its high efficiency and low EMI noise.

In conclusion, the RAC15-05DA-E-ST AC DC converter is an innovative product that has wide-ranging application in many industries. It features a high efficiency ratio, low cost, small size and an ultra-wide input voltage range. Understanding how the device works also requires an understanding of the underlying principles of AC-DC conversion. This device is primarily used in applications requiring power from AC mains that may have a wide input voltage range, making it especially suited for LED lighting, PLCs, medical e-devices, motor drives, industrial electronics, solar power components, and refrigerator & air conditioning systems.
