Centralized Emergency Units177

Battery-powered units: DINN Series

The DINN units are uninterrupted power supply sources formed basically of a sealed NiCd home storage batteryand an electronic control circuit. They supply a DC voltage output. The electronic control circuit isexecuted with cold technology. This favours operating conditions and lengthens the life of the storagecells. These units include charger protection against excessive consumption, protection against shorts at the output, protection against incorrect mains connection and protection against a faulty battery.
