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.
