APPLICATIONS
200
20
The WRB_SP-3W & WRA_SP-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:

*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.

Note:
capacitance properly or choose capacitors with
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
safe and reliable operation is ensured, the
greatest capacitance of its filter capacitor sees

1. All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated output load
unless otherwise specified.

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 supply
should afford the startup current of this kind of
DC/DC module. (Figure 2)

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.
