APPLICATIONS
The WRA_SP-2W 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 =1500VDC);
3) Where the regulation of the output
voltage and the output ripple noise are
demanded.

supply and the rippled voltage do not exceed
the module standard. Input current of power
supply should afford the startup current of this
kind of DC/DC module. (See figure 2)
External Capacitor
Although this series of DC/DC converter can
work without external capacitor, in order to keep
an optimum performance, however, it needs
external capacitor. (See Table 1)

Requirement on Output Load
To ensure this module operate efficiently and
reliably, a minimum load is specified for this kind
of DC/DC converter in addition to a maximum
load (namely full load). During operation, make
sure the specified range of input voltage is not
exceeded, the minimum out put load is not less
than
10%
Of the full load, and that this product

should never be operated under no
load!!!
If the actual load is less below the
specified minimum load, the output ripple of this
type of DC/DC converter will increase
drastically and at the same time efficiency &
reliability of the circuit will decrease deeply .If
the actual output power from the load in your
circuit is very small, please connect a resistor
with proper resistance at the output end to in
parallel to increase the load, or use our
company’s other products with a lower rated
output power.

Note: All Pins on a 2.54mm pitch; All Pin diameters are 0.50 mm(Tolerance:±0.15);
All the WRA_SP-2W 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 & 2). 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 1).If you want to use the products in high EMI, please choose our metal packaged products.
