Note:
1.*Input voltage can't exceed this value, or will cause the permanent damage.
2. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
3. Operation under 10% load will not damage the converter; However, they may not meet all specification
listed.
APPLICATIONS
The
WRE_ZD-6W&WRF_ZD-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≤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.

Requirement Output Load
In order to ensure the product operate efficiently and eliably, 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 WRE_ZD-6W & WRF_ZD-6W Series have been tested
according to the following recommended
leaving factory. (See Figure 1).

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
