group of polar power supplies are isolated from
the input power supply in a distributed power
supply system on a circuit board.

These products apply to:
1) Where the voltage of the input power supply
is fixed (voltage variation ≤ ±10%);

2) Where isolation is necessary between input
and output (isolation voltage ≤1000VDC);
3) Where the regulation of the output voltage
and the output ripple noise are not
demanding.
