The WRA_CS-3W & WRB-CS-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.

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≤1500VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

*Input voltage can’t exceed this value, or will cause the permanent damage.
Note: The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
Operation under 10% load will not damage the converter; However, they may not meet all specification listed.

If you want to further decrease the
input/output ripple, an “LC” filtering network may
be connected to the input and output ends of the
DC/DC converter, see (Figure 1).

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. The
preceding power source must be able to provide
for converter sufficient starting current Ip (Figure

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:
