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.

Circuit
All the WRA_ZMD-10W&WRB_ZMD-10W Series have been tested ccording
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).General:
Cin: 10μF-47μF
Cout: 10μF/100mA

When open or high impedance,the converter work well; When this pin is
‘high’; the converter shutdown; It should be note that the input current (Ic)
should between 5-10mA, exceeding the maximum 20mA will cause
permanence damage to the converter.
The value of R Can be derived as follows :

While using unstable power source,please ensure the output voltage and
ripple voltage do not exceed indexes of the converter.The preceding power
source must be able to provide for converter sufficient starting current
