The WRA_YMD-3W&WRB_YMD-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 the regulation of the
Output voltage and the output
ripple noise are demanded.

Converter.Make sure the specified 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.

WRA-YMD-3W＆WRB-YMD -3W Series
APPLICATION NOTE
Recommended Circuit
All the WRA_YMD-3W&WRB_YMD-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 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).General:
Cin:
5V&12V
100μF
24V&48V
10μF-47μF
Cout: 10μF/100mA
Input current
While using unstable power source,please ensure the output voltage and ripple voltage do not exceed
indexes of the converter.The preceding power source must be able to provide for converter sufficient
starting current Ip(Figure 2).General:Ip≤1.4*Iin-max
No parallel connection or plug and play

Use dual output simultaneously,forbid opening
output pin (0V) to use as single output.
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°C, humidity<75%, nominal input voltage and rated output load unless
otherwise specified.
4. In this datasheet, all the test methods of indications are based on corporate standards.
5. Only typical models listed, other models may be different, please contact our technical person for more details.
