Description
QUINT DC/DC converter – superior system availability from
SFB technology
Compact DC/DC converters from the new QUINT POWER
generation maximize your system availability. With SFB
technology (Selective Fuse Breaking Technology), 6-fold
nominal current for 12 ms, it is possible to trigger even standard
circuit breakers reliably and quickly. Faulty current
paths are switched off selectively, the fault is located, and
important system parts remain in operation. Comprehensive
diagnostics are provided through constant monitoring of the
input voltage, output voltage and output current. Preventive
function monitoring visualizes critical operating states and
indicates them to the controller before errors can occur.
The application fields for DC/DC converters are numerous
– Changing the voltage level
– Refreshing the output voltage for constant voltage at
the end of long cables
– Setup of independent supply systems by electrical isolation

Features
– Wide-range voltage input
