A_S-2WR3 & B_S-2WR3 series are specially designed for applications where an (two) isolated voltage is required in a distributedpowersupply system. They are suitable for: 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 output regulation is not as strict
