HIGH EFFICIENCY 160W AC-DC POWER SUPPLY
SFA160 SERIES - 100W TO 160W
DS1_SFA160 SERIES_REV05 JUNE 2012

DESCRIPTION
The SFA160 is a series of high efficiency, small form
factor and single output AC-DC power supplies.
Offering 160 W of regulated DC power from in an
industry standard 2x4x1 in open-frame form factor,
the SFA160 series consumes 46% less space in a
system, enabling designers to offer smaller systems
or to integrate more advanced features into their
system without compromising on system size.
By converting energy at >90% efficiency, the
SFA160 generates less heat facilitating higher
reliability and space saving designs.

2 YEAR WARRANTY

The SFA160 series is available in four different high
power output voltages at 5, 12, 24 and 48 V and is
equipped with an auxiliary low power 12 V output,
which can be used as the supply voltage for an external fan.
