Telecom Shelter

Telecom Shelter is a "small building" that contains telecom equipment away from main switching centers. The building usually can be trucked over the road and connected to local utility. It has attached backup systems to provide an interconnection and or local service.

Telecom Shelters is often powered through various sources which include - AC/DC line supply, battery supply and Diesel generator. To increase the reliability of the telecom shelter, people ofent use Solar energy together battery to power the system if necessary. And wind mill powered shelter is getting popular too. 

Fairchild has the following solutions such Power Management ICs, Power MOSFETs and IGBTs, plus analog and digital gates in the telecom shelter applications.
