DC DC converters are electrical and electronic devices that convert direct current (DC) from one voltage level to another. The RP100H-4848SRW/P-HC, specifically, is a high current, high power grid-tied converter for low voltage industrial applications. It can accept DC input from 6 to 50V, and provides a regulated DC output of 48V, up to 100A.

The RP100H-4848SRW/P-HC has a wide range of applications ranging from automotive, medical to industrial, due to its brushless, low-noise design with a temperature range of -30° to +75°C. It features high power efficiency, current limiting, under-voltage lockout and short-circuit protection functions. The device is compliant with international safety standards.

The working principle of the RP100H-4848SRW/P-HC involves step-down, or buck conversion. In a buck regulator, an inductor is connected in series with the output of a DC voltage source. A switching device is connected in parallel with the inductor. A diode is also connected in parallel with the inductor. When the switching device is activated, a DC current flows through the inductor, allowing current to be maintained in the circuit. When the switching device is deactivated, the magnetic field stored in the inductor induces a voltage in its opposite direction, opposing the input voltage. This reverse voltage is what is seen at the output of the DC DC Converter.

The current limiting, and other protection functions, are provided by comparing the input voltage, output voltage, and cycling the switching device, based on the differences between the two voltages. These protection functions prevent the device from over-delivering on current, and protect it from unexpected voltage changes.

The RP100H-4848SRW/P-HC is ideal for applications where high current and power are required with low voltage input. Its wide range of applications and efficient design make it a perfect candidate for energy storage systems, battery backup applications, or any other low voltage industrial application.
