APPLICATIONS

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.
