APPLICATIONS
The D_NXT-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 and noise are not demanding.
Such as:purely digital circuits , ordinary low frequency
analog circuits and IGBT power device driven circuits,
etc.
