APPLICATIONS
OUTPUT SPECIFICATIONS
The A_XM-1W&B_XLM-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%);
10% to 100% full load(5V output)
10% to 100% full load(9V output)
10% to 100% full load(12V output)
10% to 100% full load(15V output)
10% to 100% full load(24V output)

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.
