The A_T-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.

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.
