E_D-1WR2 & F_D-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 and load regulation;
4.Such as: pure digital circuits, low frequency analog circuits, relay-driven circuits and data switching circuits.

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
To ensure the module work efficiently and reliably, during the operation, the min. output load should be no less than 10% of the full load. If
the actual output power is low, please connect a resister to the output terminal in parallel, with a recommenced resistance which is 10% of
the rated power, and derating is required during operation.
