APPLICATIONS
The KRB_D-3W~10W Series are specially
designed for applications where a wide
range input voltage power supplies a
reisolated 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: 2:1);
2) Where the regulation of the output
voltage and the output ripple noise a
redemanding.
These products don’t apply to:
1) Where the input voltage t is required to be
more than 2:1;
2) Where the isolation voltage between
input and output is required;
�?
Input voltage above it may cause permanent damage to the device.
