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. Within ±30% of rated input voltage, it can be executed at full-load operation and operate properly; with±40% of rated input voltage, it can withstand that for 1 second. Input Under-Voltage Protection If input voltage drops below Vimin, the internal control IC shuts down and there is no output voltage. It recovers automatically when input voltage reaches above Vimin, please refer to the cruve below.

Hold-up Time D and F and E-5 types are in compliance with S2 level, while B and C and E types are in compliance with S1 level at full load output condition. To fulfil the requirements of S2 level, B and C and E types require de-rating their output load to 70%, please refer to the curve diagrams below.

This is only for redundant use (increase the reliability of the system) and users have to check suitability of the circuit by themselves. + I/P D1 EIN PS1 RL I/P - + I/P D2 PS2 I/P - 2.When using S.P.S. in parallel connection, the leakage current will increase at the same time. This could pose as a shock hazard for the user. So please contact the supplier if you have this kind of application. B.Operation in Series RSD-300 can be operated in series. Here are the methods of doing it: 1.Positive and negative terminals are connected as shown as below. According to the connection, you can get the positive and negative output voltages for your loads. + +V I/P E IN PS1 RL I/P - COM + I/P PS2 RL I/P - -V 2.Increase the output voltage (current does not change). Because RSD-300 series have no reverse blocking diode in the unit, you should add an external blocking diode to prevent the damage of every unit while starting up. The voltage rating of the external diode should be larger than V1+V2 (as shown as below). + +V I/P E IN PS1 V1 D 1 I/P - V1+V2 R L + I/P PS2 V2 D 2 I/P - -V File Name:RSD-300-SPEC 2018-01-15 EFFICIENCY EFFICIENCY EFFICIENCY EFFICIENCY EFFICIENCY EFFICIENCY EFFICIENCY EFFICIENCY 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. Please note that it's not suitable to operate within the overload region continuously, or it may cause to over temperature and reduce the life of the power supply unit or even damage it. Vo(%) 100 Overload 50 region Io(%) 0 50 100 150 Over Voltage Protection The converter shuts off to protect itself when the output voltage drawn exceeds 115~140% of its output rating. It must be repowered on to recover. Over Temperature Protection The converter shuts off to protect itself when the built-in temperature sensor mounted on the main power transformer senses a high temperature. The output recovers automatically if the temperature drops below the limit. LED Indicator Equipped with a built-in LED indicator, the converter provides an easy way for users to check its condition through the LED indicator. Green : normal operation; No signal: no power or failure. Derating Curve a.Single unit operation If the unit has no iron plate mounted on its bottom, the maximum ambient temperature for the unit will be 55℃ as operating under full load condition.

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. The size of the suggested iron plate is shown as below. In order for optimal thermal performance, the iron plate must have an even & smooth surface and RSD-300 series must be firmly mounted at the center of the iron plate.
