PROTECTION

1. All parameters NOT specially mentioned are measured at 24,48VDC input, rated load and 25 of ambient temperature.℃

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

3. Tolerance : includes set up tolerance, line regulation and load regulation.

4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets

EMC directives. For guidance on how to perform these EMC tests, please refer to EMI testing of component power supplies.

RSD-300 300W Railway Single Output DC-DC Converter series Input Reverse Polarity Protection There is a MOSFET connected in series to the negative input line. If the input polarity is connected reversely, the MOSFET opens and there will be no output to protect the unit. Input Range and Transient Ability The series has a wide range input capability.

300W Railway Single Output DC-DC Converter RSD-300 series Overload Protection If the output draw up to 105~135% of its output power rating, the converter will go into overload protection which is constant current mode. After the faulty condition is removed, it will recover automatically. Please refer to the diagram below for the detail operation characteristic.

300W Railway Single Output DC-DC Converter RSD-300 series Suitable installation methods are shown as below. Since RSD-300 is a semi-potted model, its thermal performances for the following installation methods are similar and share the same derating curve. b.Operate with additional iron plate If it is necessary to fulfil the requirements of EN50155 TX level that operate the unit fully-loaded at 70℃, RSD-300 series must be installed onto an iron plate on the bottom.
