The PES2-Series are specially designed for applications with a
wide input voltage range. 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 up to 2:1 range
2) Where isolation is necessary between input and output
3) Where the regulation of the output voltage and the output ripple
noise are demanded.
All specifications typical at Ta=25°C, nominal input voltage and full load unless otherwise specified

App Notes
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.
Recommended testing circuit
All the PES2-Series have been tested according to the following recommended
testing circuit before leaving factory. This series should be tested under load. (See
Figure)
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
EXTERNAL CAPACITOR TABLE
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.

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 flash startup
current of this kind of DC/DC module.
General: Ip ≤1.4*Iin-max:
No parallel connection or plug and play.
