APPLICATIONS
The E_KS-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.
