WRB4815YES-2W OUTPUT SPECIFICATIONS DESCRIPTION The WRB-YES-1W&WRB-YES-2W series are specially designed for applications where a group of polar 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.

Lin 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).

No parallel connection or plug and play. Note: 1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically. 2. Operation under 10% load will not damage the converter; However, they may not meet all specification listed. 3. All specifications measured at Ta=25℃, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 4.
