DC-DC converters are widely used in many fields. The most important feature of a DC-DC converter is to regulate the magnitude and direction of the power flow. Normal DC-DC converters are designed to accept a voltage input and to output voltage in the same direction as the input. However, there are a variety of different types of DC-DC converters, including isolated DC-DC converters, switch mode DC-DC converters, and converters that can invert the direction of power flow.

The SRAH-02A1AFR is an isolated DC-DC converter manufactured by Mean Well. It features an ultra-wide 4:1 input voltage range of 18 to 75V, making it especially suitable for industrial and automotive applications. The output voltage can be adjusted via a voltage sense wire, allowing users to set the output within a range of 3V to 5V.

The SRAH-02A1AFR is designed to provide a smooth, low noise output that is ideal for industrial and automotive applications. It is equipped with a wide-range temperature drift compensation function, ensuring its stability and reliability. The on-board EMI filter helps to minimize noise interference, while the built-in remote ON/OFF control allows users to easily control the power of their device.

The SRAH-02A1AFR utilizes a special design principle to achieve maximum efficiency and provide high noise immunity. This simplified push-pull topology converter adopts a patented synchronous rectification scheme which allows it to operate at high efficiency across a wide load range. It also features active input current limitation and short-circuit protection, helping to protect the converter under extreme conditions.

The SRAH-02A1AFR’s patented synchronous rectification architecture enables it to provide clean, regulated power to the system at all times. The device’s internal circuitry is designed with a dual-loop architecture which combines regulation and power factor correction. This ensures that the input current waveform remains close to the ideal sinusoidal shape even with a wide input voltage range.

The SRAH-02A1AFR combines the functions of voltage regulation, power factor correction, and isolation in a single unit. Its wide operating temperature range and high surge capability make it suitable for various industrial applications. With a power density of up to 88 W/in3, the SRAH-02A1AFR is an ideal choice for space-constrained industrial projects.

In conclusion, the SRAH-02A1AFR is an isolated DC-DC converter offering high efficiency, wide input voltage range, and excellent noise immunity. It provides a regulated output in various configurations, as well as a wide range of features such as remote ON/OFF and active current limitation. The innovative design of the device delivers high performance and reliability for industrial and automotive applications.
