APPLICATIONS

The IF_S-1W & IF_D-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.

These products apply to:

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

≤3000VDC);

3) Where the regulation of the output voltage and the output ripple noise

are demanded.
