These products apply to: 1) Where the voltage of the input power supply is fixed (voltage variation 10%); 2) Where isolation is necessary between input and output (isolation voltage 3000VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanding. Such as: purely digital circuits, ordinary low frequency analog circuits, and IGBT power device driving circuits. MODEL SELECTION Note: The E_S-W25/F_S-W25 series also are available in our company.

Note: 1.All specifications measured at TA=25C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 2.Dual output models unbalanced load: 5%. DC DC (Figure 1) GND 0V 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 recommended capacitance of its filter capacitor sees (Table 1).

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 (E_S-W25&F_S-W25).
