MODEL SELECTION WR WRD D①05②05③05④Y⑤ D⑥-3W⑦ ①Product Series ③1st Output Voltage ⑤Wide (2:1) Input Range ⑦Rated Power ②Input Voltage ④2nd Output Voltage ⑥Package Style APPLICATIONS The WRD_YD-3W series are specially designed for applications where a wide range input voltage power supplies are isolated from the input power supply in a distributed power supply system on a circuit board. 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 Voltage≤1500VDC); 3)Where isolation is necessary between Vout1 and Vout2 (Isolation Voltage≤1000VDC); 4)Where the regulation of the output voltage and the output ripple noise are demanded.

APPLICATION NOTE 1) Requirement On Output Load In full order to ensure load), a minimum input voltage less than reliability the load product is is not exceeded, will reduce for efficiently this kind the minimum output the specified minimum resistor as extra operate specified greatly. load, If the the load no output actual and reliably, in addition to a max load (namely of DC/DC converter. Make sure the specified less than 10% ripple may increase output power is very load. sharply small, If while please the its add range actual load efficiency an of is and appropriate loading, or contact our company for other lower output power products. 2) Recommended Circuit All the WRD-YD-3W Series have been tested according to the following recommended testing circuit before leaving factory. This series should be tested under load (see Figure 1). If you want to further choose capacitors with start-up problem. If low decrease the input/output ESR. However, you want to use the the ripple, capacitance products in you can should high increase not EMI, be capacitance too high, properly or may or cause please choose our metal packaged products (WRD_YD-3W). For every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1).
