A general power failute in an electrical Cabinet is a major failure that affects all the luminaires (or other equipment) powered from the Cabinet. Tellink Streetlghting Cabinet Remote Management system is capable of detecting this situation and reporting and alarm to the maintenance team.

To perform this function, no external batteries or uninterruptible power supply (UPS) are needed. Tellink Control and Communications Unit (UCC) includes an internal backup power mechanism that allows to implement this function without the need for additional equipment, thereby saving money and space in the electrical Cabinet.
