APPLICATIONS
The WRE_ZD-3W&WRF_ZD-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≤4:1);
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.

APPLICATION NOTE
Requirement Output Load
Min Typ. Max Uni
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.

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). General:

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), General:
