Input current Input Current(A) When the electricity is provided by the unstable power supply, please make sure that the range of the output voltage fluctuation and the ripple voltage of the power supply do not exceed the indicators of the modules. Input current of power supply should afford the flash startup current of this kind of DC/DC module(see Fig. 5). Generally: Vin=5V Iave =1297mA Vin=12V Iave=649mA Vin=24V Iave=307mA Vin=48V Iave =158mA Iave Input Voltage scope Input Voltage (V) Fig. 5 4. Output load requirements To ensure that the module can work efficiently and reliably, its output min. load shall be no lower than 5% of the rated load when using, or the output ripple may increase rapidly. Ensure that the product working load must be higher than 5% of the rated load. 5.
