These products apply to: 1) where the voltage of the input power supply is fixed (voltage variation ≤±5%); 2) where isolation is necessary between input and output (isolation voltage ≥1000VDC); 3) where the regulation of the output voltage and the output ripple noise are demanded.

Recommended circuit Continuous Short circuit protection Requirement on output lo ad K hours 2.1 g 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 (Figure 1). *Supply voltage must be discontinued at the end of short circuit duration. TYPICAL CHARACTERISTICS Temperature Derating Graph 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).

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.or use our company's products with a lower rated output power . No parallel connection or plug and play. Use dual output simultaneously, forbid opening output pin(0V)to use as single output. RoHS COMPLIANT INFORMATION Microdc Professional Power Module,Inc.
