DescriptionAs well as voltage conversion, this series provides input/output isolation, allowing
use of negative ground electronics on off-highway vehicles which typically employ
positive ground battery systems. May also be used as a Voltage Stabilizer for sensitive
equipment. Offers protection against line transients and voltage spikes typically
caused by large DC motors and switching transients often encountered on fork lifts,
locomotives and light rail. A special circuit clamps input spikes to a safe level,
protecting both the converter and the powered equipment. This product series is
further enhanced with extra rugged construction of case and internal components
for severe vibration applications.
