Note: The load shouldn't be less than 10%, otherwise ripple will increase dramatically. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.

APPLICATIONS

The WRA_YMD-6W/WRB_YMD-6W 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 the regulation of the output voltage and the output ripple noise are demanded.

Make sure the spec ified range of input voltage is not exceeded, the minimum output load no less than 10% load. If the actual load is less than the specified minimum load, the output ripple may increase sharply while its efficiency and reliability will reduce greatly. If the actual output power is very small, please add an appropriate resistor as extra loading, or contact our company for other lower output power products. Recommended Circuit All the WRA_YMD-6W & WRB_YMD-6W Series have been tested accor ding to the following recommended testing circuit before leaving factory. This series should be tested under load. Never be tested under no load (see Figure 1). DC DC Vin GND +Vout Cin Vin GND +Vout 0VCin DCDC -Vout Dual Output Single Output (Figure 1) If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR. 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).
