The WRE_P-3WR2 & WRF_P-3WR2 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. For these DC-DC converters, you can reduce
the failure points of design, and save the manpower, material and time cost in developing micro power supply, and also ensure better
quality, stability, safety protection, and reliability for the end products.
These products apply to where:
1) Where the voltage variation range of the input power supply ≤ 2:1;
2) Where isolation is necessary between input and output (isolation voltage ≤3KVDC);
3) Where high requirements for the output voltage stability and output ripple noise are applied;
In circuits such as industrial control, electric power, communication system power supply, etc.

Design Reference
1. Output load requirements
To ensure that the module can work efficiently and reliably, its output min. load shall be no lower than 5% of the rated load when using, or
the output ripple may increase rapidly. Ensure that the product working load must be higher than 5% of the rated load.
2. Typical application
All the DC/DC converters of this series are tested according to the recommended circuit (see Fig. 2) before delivery.
If it is required to further reduce input and output ripple, properly increase the input & output of additional capacitors Cin and Cout or
select capacitors of low equivalent impedance provided that the capacitance is no larger than the max. capacitive load of the product.

Note: Note: the min. distance of the bonding pads between input grounding and output grounding shall be ≥ 2mm.
4. Input current
When the electricity is provided by the unstable power supply, please make sure that the range of the output voltage fluctuation and the
ripple voltage of the power supply do not exceed the indicators of the modules. Input current of power supply should afford the flash startup
current of this kind of DC/DC module(see Fig. 5).
