APPLICATIONS
The MA_XD-1W & MA_XD-2W 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)
2)
3)
Where the voltage of the input power supply is fixed
Where isolation is necessary between input
Where the regulation of the output voltage and
and
the
(voltage variation≤±5%);
