APPLICATIONS
The 2A_XSR series are specially designed
for applications where a group of polar 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 fixed (voltage variation ≤±5%);
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 demanded.

To get an extreme low ripple,an "LC" filtering network
may be connected to the input and output ends of the
DC/DC converter, which may produce a more significant
filtering effect.It should also be noted that the inductance
and the frequency of the "LC" filtering network should be
staggered with the DC/DC frequency to avoid mutual
interference (see figure 1).

In some circuits which are sensitive to noise and ripple,
a filtering capacitor may be added to the DC/DC output
end and input end to reduce the noise and ripple.
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 the
EXTERNAL CAPACITOR TABLE (see Table 1).
*Supply voltage must be discontinued at the end of short circuit duration.

When the environment temperature is higher than 71℃,
the product output power should be less then 60% of the
rated power.
No parallel connection or plug and play.
Use dual output simultaneously, forbid opening output
pin (0V) to use as single output.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise
specified.Another 24V products, please inquire Our technical department!
Requirement on output load
To ensure this module can operate efficiently and reliably, During operation, the minimum output load is
not less than 10% of the full load, and that this product should never be operated under no load! If the
actual output power is very small, please connect a resistor with proper resistance at the output end in
parallel to increase the load.or use our company's products with a lower rated output power (IA_XS-1W
series).
