APPLICATIONS
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.
These products apply to:
1) Where the voltage of the input power supply
is wide range (voltage range2:1);
2) Where isolation is necessary between input
and output(Isolation Voltage1500VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

APPLICATION NOTE
1) CTRL Terminal
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 converterThe value of
R can be derived as follows:
R= Vc-VD-1.0
Ic
2) Recommended circuit
If you want to further decrease the input/output ripple, an LCfiltering 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).
General: Cin: 12V 100μF
24V 10μF-47μF
Cout: 100uF(Typ.)
Lin: 4.7μH -120μH
Lout: 2.2μH-10μH
Cs: 10μF-47μF
3) Input current
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 2). General: Ip 1.4*Iin-max
4) No parallel connection or plug and play

Note:
1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
2. Operation under 10% load will not dam age the converter; However, they may not meet all specification listed.
3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
4. In this datasheet, all the test methods of indications are based on corporate standards.
5. Only typical models listed, other models may be different, please contact our technical person for more details.
