7 / 10 page 30W Reliable Railway DC-DC Converter R S D - 3 0 series Over Voltage Protection LED Indicator 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. 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. 2.Increase the output voltage (current does not change). Because RSD-30 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). - I/P + I/P PS2 2 V I/P - E IN PS1 I/P 1 + V -V D 2 V1+V2 L R 1 D +V 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. 0 50 100 150 50 100 Vo(%) Io(%) Derating Curve AMBIENT TEMPERATURE (℃) 100 10 0 20 40 60 80 -40 20 30 40 50 55 60 70 (HORIZONTAL) Overload region a.Single unit operation de-rating output current when ambient temperature is between 55~70 , please refer to the de-rating curve as below. ℃ 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.
