APPLICATIONS
The M2WWRA-B_SP 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.

If you want to further decrease the input/output
ripple, you can increase 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 (Table 1).

TYPICAL CHARACTERISTICS
Input Current
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)
