A_S-1WR2 & B_LS-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
≤1500VDC);
3.Where do not has high requirement of line regulation and load regulation;
Such as: pure digital circuits, low frequency analog circuits, relay-driven circuits and data switching circuits.
