DC-DC converters are essential components for many electronic applications and can provide power to a device in a variety of ways. The RSO-243.3S is a high-efficiency, zero-voltage switching (ZVS) resonant converter designed for applications ranging from 24V to 36V input, designed to deliver an output up to 20W. Whether used for test and measurement equipment, industrial controls, as an auxiliary power supply, or simply power an LED lighting system, the RSO-243.3S is capable of delivering a wide range of output voltages and currents.

The RSO-243.3S is based on D1H Series of DC/DC converters and utilizes a resonant topology for power conversion. The ZVS switching method, also known as Soft-Switching, is a switching mode that reduces EMI (electromagnetic interference) and related noise. This type of resonant converter is able to switch using high switching frequency with minimal power losses. This combination of ZVS switching and high switching frequency makes the RSO-243.3S an ideal solution for applications where noise, efficiency, and reliability is paramount.

The RSO-243.3S is designed to provide a constant output voltage of 12V/3A, 24V/1.6A, or 36V/0.83A, depending on the input voltage. An external control circuit or the onboard potentiometer can be used to adjust the output voltage to nonstandard values in a nominal range of 6-48V. The output voltage is provided via an isolated connection and can be used to power a variety of applications such as measurement equipment, control loops, LEDs, and other electronic circuits.

The RSO-243.3S operates on a fixed frequency switching mode of 100 KHz. The switching frequency can be adjusted, if needed, to meet the required output voltage range. The non-isolated connection on the output side of the converter contains two pins which act as discharge pins. These pins allow the converter to safely discharge any capacitance present on the output side, ensuring safe operation.

The RSO-243.3S is designed with extreme efficiency in mind, allowing it to reach >92% conversion efficiency without the need of any active cooling. Further, the on-board thermal shutdown feature will automatically shut down the converter in the event of overheating, allowing the device to cool down before resuming operation.

The RSO-243.3S offers features such as soft start, over current protection, over voltage protection, and short circuit protection. This robust protection system allows the use of the RSO-243.3S in a variety of demanding applications, while still remaining safe and reliable.

The RSO-243.3S is a highly efficient, reliable, and safe DC/DC converter. By combining the simplicity of ZVS switching with high switching frequency and the features offered by the on-board protection system, the RSO-243.3S is an ideal choice for applications demanding reliable and efficient power conversion.
