DESCRIPTION
The WRE_YD-6W&WRF_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 (voltage range ≤2:1);
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.

RECOMMENDED CIRCUIT
APPLICATION NOTE
1) 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.
2) Recommended Circuit
All the WRE_YD-6W&WRF_YD-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:
General: Cin: 5V&12V
24V&48V 10µF-47µF
Cout: 10µF/100mA
100µF
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(See figure 2),
