APPLICATIONS
The A_XMS&B_XLMS 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.
