It offers a wide range of features, including high efficiency, high power conversion, and wide input and output voltage ranges. In this article we will look in detail at the application fields and working principles of this converter.

Application Field

The REC15-4812D/H2 DC DC converter is designed to be used in a variety of different applications. It is ideal for air compressors, battery chargers, electrical vehicles, LEDs, industrial motor control systems, and power adapters. It is also used in power conditioning systems, DC DC/AC converters, power supplies, and UPS (Uninterruptible Power Supplies). It abides by EN 55012:1998 electromagnetic compatibility requirements.

Power Ratings and Features

The converter offers a wide input voltage range of 12 to 48V and an output voltage range of 12 to 48V. It provides a maximum output power of 15 watts and a maximum continuous current of 4.2A. It has a high efficiency of up to 92%, making it an excellent choice for a wide range of power conversion applications. It is designed to meet EN 55012:1998 electromagnetic compatibility requirements and is fully protected against over voltage, over temperature, overload, and short circuit. It is also designed to be self-commutating, reducing the need for manual adjustment during operation. Additionally, it features a wide temperature range operation of -40°C to +85°C.

Working Principle

The REC15-4812D/H2 DC DC converter works in half-bridge mode. It uses an input voltage of 12 to 48V and outputs a regulated voltage of 12 to 48V, depending on the output load. It uses two sets of power MOSFETs to switch the power conversion process. When the input voltage is greater than the output voltage, the top MOSFET will conduct, allowing the output voltage to increase. When the input voltage is less than the output voltage, the bottom MOSFET will conduct, allowing the output voltage to decrease. This switching action occurs repeatedly until the two voltages reach equilibrium. The converter also contains an internal feedback controller to ensure that the output voltage is accurately regulated.

Safety Improvements

This DC DC converter has several safety protections in place in order to ensure safe and reliable operation. It includes over-voltage, over-current, overload, and short circuit protection, preventing damage to internal components. It also contains a current shunt for accurately monitoring the current draw and a temperature sensor for temperature control. Furthermore, the converter is UL, cUL, CE, CB, and EN approved, meeting the highest safety standards.

Conclusion

The REC15-4812D/H2 DC DC converter is designed with several features and protections for safe and reliable operation. It is designed to work in half-bridge mode and can provide up to 15 watts of power with a wide input and output voltage range. It meets the electromagnetic compatibility requirements of EN 55012:1998 and features a wide temperature range operation of -40°C to +85°C. The converter is an ideal choice for a wide range of power conversion applications, including air compressors, battery chargers, electrical vehicles, and power adapters.
