Page 3/4 App Notes Requirement on output load To ensure this module can operate efficiently and reliably, during operation, the minimum output load is not less than 10% of the full load, and that this product should never be operated under no-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. Recommended testing circuit If you want to further decrease the input/output ripple, an “LC” filtering network may be connected to the input and output ends if the DC/DC converter, see Figure on the right hand side. 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 start-up problem might arise. For every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (see Table). Output Voltage Regulation and Over-voltage Protection 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. Overload Protection Under normal operating conditions, the output circuit of these products has no protection against over-current and short-circuits. The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. No parallel connection or plug and play.
