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.
