描述 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
