The IE_KS-1W&IE_S-1W Series are
specially designed for applications where a
group of polar power supplies are isolated
from the input power supply in a distributed
power supply system on a circuit board.

1) Where the voltage of the input power
supply is fixed (voltage variation ≤±5%);
2) Where isolation is necessary between
input and output (isolation voltage
