10. Product Application Considerations 1. Input requirements: Ensure that the output voltage fluctuation range of the power supply does not exceed the input requirements of the DC / DC module itself, and the output power of the input power supply must be greater than the output power of the DC / DC module. 2. One recommended circuit: For applications where ripple and noise requirements are normal, a filter capacitor can be connected in parallel at the input and output ends. The external circuit is shown in the following figure1 with the recommended value details of the filter capacitor. Output load requirements: Try to avoid no-load use. When the actual power consumption of the load is less than 10% of the rated output power of the module or there is no-load phenomenon, it is recommended that a dummy load be connected to the output end. The dummy load (resistance) can be calculated by 5~10% of the rated power of the module, resistance value = Uout / (1W * 10%). 3. Over-load protection: Under normal operating conditions, the output circuit of this product has no protection function against overload conditions. The easiest way is to connect a resettable fuse in series at the input end, or add a circuit breaker to the circuit. 4. The external capacitor of the output terminal should not be too large, otherwise it will easily cause over-current or poor start-up when the module starts. 5. If the product works below the minimum required load, the performance of the product cannot be guaranteed to meet all performance indications in this manual. 6. The maximum capacitive load is tested under the input voltage range and full load condition. 7. Unless special instructions, all indexes in this manual are measured at the condition, Ta = 25 ¡É, humidity <75% RH, nominal input voltage and output rated load. 8. All index testing methods in this manual are based on the company's standards 9. Our company can provide product customization, and you can directly contact our technical staff for specific conditions 10. Product specifications are subject to
