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.

In order to ensure the product operate efficiently and reliably, in addition to a max load
(namely full load), a minimum load is specified for this kind of DC/DC 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.

2) Recommended Circuit
All the WRA_YMD-6W & WRB_YMD-6W Series have been tested according 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).
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
24V&48V
100μF
10μF-47μF
Cout: 10μF/100mA
3) Input Current
When it is used in unregulated power supply, be sure that the fluctuating range of the power
supply and the rippled voltage do not exceed the module standard. Input current of power
supply should afford the startup current of this kind of DC/DC module (Figure 2).
General: Ip ≤1.4*Iin-max
4) 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. Capacitor MAX load tested at input voltage range and full load.
4. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
5. In this datasheet, all the test methods of indications are based on corporate standards.
6. Only typical models listed, other models may be different, please contact our technical person for more details.
