single output
FEATURES
Continuous short-circuit protection
Operating temperature range: -40℃ to +105℃
High efficiency up to 80%
Compact SIP/DIP package
International standard pin-out
Isolation voltage: 1.5K VDC
EN60950,UL60950,IEC60950 approval

B_S-1WR2 & B-D-1WR2 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 and the ripple & noise of the output voltage 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
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%).
