APPLICATIONS
12
15
The WRA_YD-6W&WRB_YD-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
400
40
*Input voltage can’t exceed this value,or will cause the permanent damage.

APPLICATION NOTE
Requirement on output load
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.
Recommended Circuit
All the WRA_YD-6W&WRB_YD-6W 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).

While using unstable power source,please ensure the output voltage and
ripple voltage do not exceed indexes of the converter. Input current of
power supply should afford the startup current of this kind of DC/DC module
(See figure 2).

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.
