The A_D-1W & B_LD-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 ≤ ±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.

Such as: purely digital circuits, ordinary low frequency analog circuits, and IGBT power device driving circuits.
