The WRAP-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 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
demanding.
These products don't apply to:
1) Where the input voltage t is required to be
more than 2:1;
2) Where the isolation voltage between
input and output is required to be
>1000VDC;
3) The output load's actual power
consumption is less than 1W, otherwise our
company's WRAP
-
1W/0.5W series are
recommended.

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 loadthe 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
smallplease 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.
The products cannot be used in
parallel and in plug and play.

Recommended Circuit
All the WRA-3W 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.
Input Current
When it is used in unregulated power supplybe sure that the fluctuating range of the power
