A_S-2WR2 & B_S-2WR2 series are specially designed for applications where an isolated voltage is required in a distributed power supply
system. They are suitable for
1. Where the voltage of the input power supply is stable (voltage variation: ±10%Vin);
2. Where isolation between input and output is necessary (isolation voltage ≤1500VDC);
3. Where the output voltage regulation is not strictly required;
4. Typical application: digit circuit condition; normal low-frequency artificial circuit condition; relay drive circuit and data switching circuit
condition, etc.

Design Reference
1. Typical application circuit
If it is required to further reduce input and output ripple, a filter capacitor may be connected to the input and output terminals, see Fig.3.
Moreover, choosing a suitable filter capacitor is very important, start-up problems may be caused if the capacitance is too large. Under the
condition of safe and reliable operation, the recommended capacitive load values are shown in Table 1.

3. Output load requirements
When using, the minimum load of the module output should not be less than 10% of the nominal load. In order to meet the performance
parameters of this datasheet, please connect a 10% dummy load in parallel at the output end, the dummy load is generally a resistor,
Please note that the resistor needs to be used in derating.
