APPLICATIONS

The E_T-1W&F_T-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

≤3000VDC);

3) Where the regulation of the output

voltage and the output ripple noise are not

demanding.

Such as: purely digital circuits, ordinary low

frequency analog circuits, and IGBT power

device driving circuits.
