APPLICATIONS

APPLICATIONS

The 2A_XSR 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 ≤±5%);

2) where isolation is necessary between input

and output (isolation voltage≥1000VDC);

3) where the regulation of the output voltage

and the output ripple noise are demanded.
