PRODUCT PROGRAM

APPLICATIONS

The RT9-RD20D1 and RD9-R20D1 Series are

specially designed for applications where a wide

range input voltage 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

wide range(voltage range d2:1);

2) Where isolation is necessary between input

and output (Isolation Voltage d1500VDC);

3) Where the regulation of the output voltage

and the output ripple noise are demanded.
