APPLICATIONS
The 2IE-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 ≤3000VDC);
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).

*Supply voltage must be discontinued at the end of short circuit duration.
TYPICAL CHARACTERISTICS
Temperature Derating Graph
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
(Table 1).

It's not recommend to connect any external capacitor in
the application field with less than 0.5 watt output.
Overload Protection
Under normal operating conditions , the output circuit of
these products has no protection against over-current
and short-circuits.The simplest method is to connect a
self-recovery fuse in series at the input end or add a
circuit breaker to the circuit.

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, a minimum load is specified for this kind of
DC/DC converter in addition to a maximum load(namely full load).During operation, make sure the
specified range of input voltage is not exceeded,the minimum output load is
not less than 10%
of the full
load, and that this product should never be operated under no load!
RoHS COMPLIANT INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature
of 300°C for 10 seconds.
The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin
with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this
series are backward compatible with Sn/Pb soldering systems.
REACH COMPLIANT INFORMATION
This series has proven that this product does not contain harmful chemicals, it also has
harmful chemical substances through the registration, inspection and approval.
