APPLICATIONS
The 2D-NXT 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.
