E_S-1WR2 & F_S-1WR2 series is specially designed for applications where an isolated voltage is required in a distributed power supply system.
It is suitable for：
1.Where the voltage of the input power supply is stable (voltage variation: ±10%Vin);
2.Where isolation is necessary between input and output (isolation voltage ≤3000VDC);
3.Where do not has high requirement of line regulation, load regulation and low ripple noise;
4.Such as: pure digital circuits, low frequency analog circuits and relay-driven circuits.etc.

Design Reference
1. Typical application
If it is required to further reduce input and output ripple, a filter capacitor can be connected to the input and output terminals, see Fig.3.
Moreover, choosing suitable filter capacitor is very important , start-up problems may be caused by too large capacitance. To ensured the
modules running well, the recommended capacitive load values as shown in Table 1.

3. Output load requirements
In order to ensure the converter can work reliably with high efficiency, the minimum load should not less than 10% rated load when it is
used. If the needed power is indeed small, please parallel a resistor on the output side ( The sum of the efficient power and resistor
consumption power is not less than 10%).
