A_S-1W(E)R2 & B_LS-1W(E)R2 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;
4. Such as: pure digital circuits, low frequency analog circuits, relay-driven circuits and data switching circuits.

Note:①Series with suffix "-1WER2" are EMI performance optimization model. As A0512S-1WER2,the EMI performance of such products is better than conventional
models (eg A0512S-1WR2), but the short circuit performance is worse than conventional models;
②The
capacitive loads of positive and negative outputs are identical.
