APPLICATIONS
±20

The WRA_N-2W & WRB_N-2W Series are
specially designed for applications where a
wide range input voltage power supplies are
±7
isolated from the input power supply in
a
24
18-36

50
distributed power supply system on a circuit
board. These products apply to:
40
1) Where the voltage of the input power supply
is wide range (voltage range≤2:1);
9
22
12
15
16
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.
13
*Input voltage can’t exceed this value, or will cause the permanent damage.
Note: The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
Operation under 10% load will not damage the converter; However, they may not meet all specification listed.

low ESR. However, the capacitance of the
output filter capacitor must be proper. If the
capacitance is too big, a startup problem might
arise. For every channel of output, provided the

When it is used in unregulated power supply,
be sure that the fluctuating range of the power
supply and the rippled voltage do not exceed
the module standard. Input current of power

APPLICATION NOTE
Input Voltage (V)
Requirement on 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% load. If the actual load is less than the specified minimum load, the output ripple may
increase sharply while its efficiency and reliability will reduce greatly. 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.
No parallel connection or plug and play.
