Part
Number
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 dem anded.

*Input voltage can’t exceed this value, or will cause the permanent damage.
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.

TYPICAL CHARECTERISTICS
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).

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.
