DC-DC converters are power conversion systems used to step-down or step-up DC voltages. This type of power converter is widely used in industrial, telecommunication, automotive, aerospace and other applications. In particular, the REC3-4815SRWZ/H2/A/X2 series are DC-DC converters designed for the automotive industry, providing a robust and reliable solution for power conversion.

The REC3-4815SRWZ/H2/A/X2 series are ideal for in-vehicle applications such as vital (12V/24V, 48V/-48V) automotive power supply and high-power office equipment power supply. By adopting an advanced chopper control method, it can control the output voltage accurately and achieve a high conversion efficiency. The series also features a wide input voltage range, low ripple noise, over-temperature and short-circuit protection etc.

The working principle of the REC3-4815SRWZ/H2/A/X2 DC-DC converter can be divided into three parts: switch control, power conversion and feedback control. In terms of switch control, the converter contains a chopper, which is controlled by a pulse width modulated (PWM) circuit to turn on/off the output DC voltage. At the same time, the output DC voltage is converted according to the PWM control signal, that is, the PWM waveform controls the output voltage. Finally, it uses feedback control to maintain the constant input/output impedance ratio, and achieves the stability and accuracy of the output voltage.

The REC3-4815SRWZ/H2/A/X2 series are suitable for the power supply of automotive equipment, communications equipment, industrial control, and other wide range of voltage requirements. It can supply a constant output voltage with a wide input voltage range, while maintaining low ripple voltages, high power factor and high efficiency. It also features a high temperature grade and meets the environmental requirements, which makes it suitable for use in harsh environments.

The REC3-4815SRWZ/H2/A/X2 series are a highly reliable and energy-saving DC-DC converter for different applications. With the adoption of an advanced chopper control method, it ensures the stability and accuracy of the output voltage, while providing a wide input voltage range and low ripple noise.
