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);
Note: The E_T-W2/F_T-W2 series also are available in our company.
ISOLATION SPECIFICATIONS
3) Where the regulation of the output
voltage and the output ripple noise are not
demanding.
