Product Description Ordering Key
DSB 51 X X DP
DSB51XXS is a surge pro- tecting device that has been designed for 2 wires communication buses at
15V specifically for Dupline® and Smarthouse® systems. Effectively pro- tects all the system devices which are normally installed at long distances in these type of systems. In order to provide sufficient protection it is necessary
Type Selection
to install one device at each end of the communi- cation line when the dis- tance is bigger than 15m. The circuit topology con- sists of multistage protec- tion providing both com- mon and differential mode protection. The construc- tion is DIN rail mounting and the cartridge is replaceable.
