Quint dc/dc converters incorporate such features as power boost, selective fuse breaking (SFB) technology and an integrated passive interface for improved reliability and easy configuration. The converters provide a precise dc voltage and can alter voltage levels, amplify voltage at the end of long cables or enable the creation of independent supply systems by means of electrical isolation. It has a dynamic power boost with up to 200% of the rated current for up to 5 sec. when starting heavy loads. A secure passive interface facilitates monitoring alarms specific to any application.
