isolated from the input power supply in
a
distributed power supply system on a circuit
board.
These products apply to:
9
3
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 and noise are not
demanding.
