APPLICATIONS
The WRB_S-1W & WRB_S-2W series are
specially designed for applications where a wide
WRB0505S-2W
WRB0509S-2W
WRB0512S-2W
range input voltage power supplies are isolated WRB0515S-2W
from the input power supply in a distributed power _WRB1203S-1W
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);
WRB1205S-1W
WRB1209S-1W
WRB1212S-1W
2) Where isolation is necessary between input
WRB1215S-1W
and output(isolation voltage ≤1500VDC);
WRB1224S-1W
12
(9.0-18)
22
20
3) Where the regulation of the output voltage and
WRB1205S-2W
the output ripple noise are demanded.
