APPLICATIONS
±5
The URA_D-5W & URB_D-5W 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 ≤4:1);
2) Where isolation is necessary between
15
24
input and output (Isolation voltage
1500VDC);
≤
3) Where the regulation of the output voltage
and the output ripple noise are demanded.
* Designing.
* * Input voltage can’t exceed this value, or will cause the permanent damage.

Refer to recommended circuit
All the URA_D-5W & URB_D-5W 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).

1.All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated output load unless
otherwise specified.
2. See below recommended circuits for more details.
If you want to further decrease the output ripple,
you can increase capacitance properly or choose
capacitors with low ESR. However, the
capacitance should not be too high. (Table 1).
