A_S-2WR2 & B_S-2WR2 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 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.
