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 1000VDC); 3) Where the regulation of the output voltage and the output ripple noise are not demanding. Such as: purely digital circuits, ordinary low frequency analog circuits, and IGBT power device driving circuits. 12 10.8-13.2 15 13.5-16.5 24 21.6-26.4 MODEL SELECTION A0505D-1W Rated Power Package Style Output Voltage Input Voltage Product Series UL UL UL UL UL CE UL CE UL CE UL CE Note: The A_D-W 25/B_LD-W25 series also are available in our company.

Dual Output L L Vin Cin +Vo Cout *Test ripple and noise by "parallel cable" method. See detailed operation instructions at Testing of Power Converter section, application notes. 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%.

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 Operating Temp.(oC) 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 (A_D -W25/B_LD-W25 series) DC DC 0V (Figure 2) No parallel connection or plug and play.
