APPLICATIONS
The WRE_P-3W & WRF_P-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);
200
20
*Input voltage can’t exceed this value, or will cause the permanent damage.
2) Where isolation is necessary between input
and output(Isolation Voltage≤3000VDC);
3) Where the regulation of the output voltage and
the output ripple noise are demanded.
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).

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)

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.
No parallel connection or plug and play.
