Product description

The SI48D-2U5 DC power supplies are high-performance 48 V power systems characterised by high efficiency of over 90% and guaranteeing a stable power supply in the telecommunications and energy sectors. Their modular design allows the configuration to be easily adapted to the user’s needs and enables rapid servicing using hot-swap technology. The units can handle currents of up to 150 A, whilst support for multiple batteries allows for flexible adjustment of capacity and backup time. Built-in PFC circuits and temperature monitoring systems enhance operational efficiency and safety. Thanks to digital communication via the RS-485 interface, the SI48D-2U5 telecommunications power supply units enable remote monitoring and parameter logging. The technical solutions employed make these units particularly valued in large-scale installations where reliability and ease of maintenance are of paramount importance.
