SMPS - Sistemas de Fuentes de alimentación

XL Telecom & Energy Ltd., Leaders in manufacturing of Telephone Jointing Kits is bringing its expertise to manufacture Switch Mode Power supply systems in 48V in modules of 25A & 100A for powering the telecommunications networks.

XL POWERPLANT

The XL POWERPLANT has micro-controller-based modules and rectifier racks for digital control and flawless performance. Its architecture allows for easy enhancement of installed capacity by merely adding the required number of modules/racks. It is a space-saving model and occupies less floor area than Thyistor-based chargers. The XL POWERPLANT can be easily handled since it weighs less than conventional systems but has higher efficiency and a higher power factor which, in the long run, contribute to savings in running costs.

It has lower MTTR contributing to substantial reduction in breakdown time achieved by on-line replacement of module without switching off total systems and allows for parallel operation of all modules in all racks.
