[ 2 YEAR WARRANTY ]
The SIL25C is a new high density non-
isolated dc-dc converter. The converter
has a wide input range (10.2 Vdc to
13.8 Vdc) and offers a -4.5 Vdc to -5.5 Vdc
output voltage range with a 25 A load. The
series offers remote ON/OFF, over-
temperature protection and over-current
protection as standard.
The remote sense feature enables the
SIL25C compensate for voltage drops
between the converters output and the load.
With full international safety approvals
including EN60950 and UL/cUL60950 the
SIL25C reduces compliance costs and time
to market.
