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

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.

All the WR E _ Y D- 4 W&WR E _ Y D- 4 W Series have been tested a ccording to
the following recommended testing circuit before leaving factory.This series
should be tested under load( S ee f igure 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).

While using unstable power source,please ensure the output voltage and
ripple voltage do not exceed indexes of the converter. Input current of
power supply should afford the startup current of this kind of DC/DC module
( See f igure 2).
