Flatpack2 DC/DC 380V/54V system
Using the Flatpack2 DC/DC 380V/48V 3000W SHE module with Eltek’s feature-rich Smartpack2 control and monitoring unit enables sites to benefit from utilizing 380 Vdc as a transmission voltage.
Either for a competitive alternative to traditional UPS in Data Centers, or for central power plants in Telecom site expansions.
Integrating state-of-the-art, super high efficiency converter modules with Eltek’s feature rich Smartpack2 monitoring and control unit, the high performance Flatpack2 DC/DC 380V/54V Power System converts the 380 Vdc bus voltage down to a regulated 54 Vdc with a module efficiency of 98.2 %.
