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
(Isolation Voltage =1000VDC);
3) Where the regulation of the output
voltage and the output ripple noise are
demanded.

CS Pin
By connecting a low ESR capacitor between
this terminal and the pin-7 (connecting to the
anode of the capacitor), the output ripple and
noise may be further improved. Generally, the
capacitance is no greater than 100uF

Input Current
Nominal input voltage range. The input current
of the power supply must be sufficient to the
startup current (Ip) of the DC/DC module (see
Figure 2)
Output Load
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% full load. If
the actual load is less than the specified minimum
load, the output ripple will increase sharply while
its efficiency and reliability will reduce greatly. If
the actual output power is very small, a proper
resistor is needed at the output end in order to
increasing the load, or contact our company for
other lower output power products.
No parallel connection or plug and
play.

APPLICATION NOTE
Recommended Circuit
All the WRD_S-1W Series have been tested according to the following recommended testing circuit
before leaving factory. This series should be tested under load. Never be tested under no 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 should not be too high.(See table 2).If you
want to use the products in high EMI, please choose our metal packaged products.
