These products apply to: 1) Where the voltage of the input power supply is wide range (voltage range 2:1); 2) Where isolation is necessary between input and output(isolation voltage1500VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.

All specifications measured at TA=25C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 2. Test ripple and noise by "parallel cable" method. See detailed operation instructions at Testing of Power Converter section, application notes. 3. Operation under 10% load will not damage the converter; However, they may not meet all specification listed. 4. See below recommended circuits for more details. (Figure 1) 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).
