During operation, make sure the specified range of input voltage is not exceeded, the minimum output load could not be less than 10% of the full load. If the actual output power is very small, please connect a resistor with proper resistance at the output end in parallel to increase the load, or use our company products with a lower rated output power (D-NXT -W2/W5). 2) 2) 2) 2) Recommended Recommended Recommended Recommended testing testing testing testing circuit circuit circuit circuit If you want to further decrease the input/output ripple , an "LC" filtering network may be connected to the input and output ends of the DC/DC converter , see (Figure1). It should also be noted that the inductance and the frequency of the "LC" Filtering network should be staggered with the DC/DC frequency to avoid mutual interference. However , the capacitance of the output filter capacitor must be proper . If the capacitance is too big , a startup problem might arise . For every channel of output,provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1). 3) 3) 3) 3) Output Output Output Output Voltage Voltage Voltage Voltage Regulation Regulation Regulation Regulation and and and and Over-voltage Over-voltage Over-voltage Over-voltage Protection Protection Protection Protection Circuit Circuit Circuit Circuit The simplest device for output voltage regulation , over-voltage and over-current protection is a linear voltage regulator with overheat protection that is connected to the input or output end in series (Figure2). 4) 4) 4) 4) Overload Overload Overload Overload Protection Protection Protection Protection Under normal operating conditions , the output circuit of these products has no protection against overload . The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. 5) 5) 5) 5) Cannot Cannot Cannot Cannot use use use use in in in in parallel parallel parallel parallel and and and and hot hot hot hot swap swap swap swap APPLICATION APPLICATION APPLICATION APPLICATION APPLICATION APPLICATION APPLICATION APPLICATION NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE RECOMMENDED RECOMMENDED RECOMMENDED RECOMMENDED RECOMMENDED RECOMMENDED RECOMMENDED RECOMMENDED CIRCUIT CIRCUIT CIRCUIT CIRCUIT CIRCUIT CIRCUIT CIRCUIT CIRCUIT EXTERNAL EXTERNAL EXTERNAL EXTERNAL CAPACITOR CAPACITOR CAPACITOR CAPACITOR TABLE TABLE TABLE TABLE (TABLE (TABLE (TABLE (TABLE 1) 1) 1) 1) It's not recommended to connect any external capacitor in the application field with less than 0.5 watt output.
