B1215S-1WR2 series is designed for use in distributed power supply systems and is especially suitable in applications such as pure digital circuits, low-frequency analog circuits, relay-driven circuits, and data switching circuits, where: 

1. The voltage of the input power supply is relatively stable with a variation of ±10%Vin or less;

2. An input-to-output isolation voltage of up to 1500VDC is necessary;

3. The requirement for a tight line and load regulation is not as strict.
