APPLICATIONS
The WRD_S-1W 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 2:1);
2) Where isolation is necessary between input
and output& Vout1 and Vout2(Isolation
Voltage1000VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

TYPICAL TEMPERATURE CURVE
Recommended Circuit
If you want to further decrease the
input/output ripple, you can increase
capacitance properly or choose capacitors with
low ESR (Figure 1).

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

CS Pin
By connecting a low ESR capacitor between this terminal and the pin-7(Figure 1), the output
ripple and noise may be further improved. Generally, the capacitance is no greater than 47uF
Output Load
To ensure this module can operate efficiently and reliably, During operation, the minimum
output load is not less than 10% of the full load, If the actual load is less than the specified
minimum load, the output ripple may increase sharply. 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.
