ISOLATION SPECIFICATIONS
APPLICATIONS
The D_NXT-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) 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.
