APPLICATIONS
The E_T-W2&F_T-W2 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.

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.
