Read MoreThe Eltek by Powerbox Flatpack S 9kW 3U Powercore with DC/DC Shelf is a high-density, modular DC power system engineered for reliable performance in telecom, industrial, and security environments. With stock available locally, it’s the perfect solution for projects requiring scalable and efficient DC power.
This 3U PowerCore system can be configured with 5 × Flatpack S HE Rectifier Modules and 4 × Flatpack 2 DC/DC Modules, delivering flexible power conversion and output capability.
The system provides a nominal –48 V DC output (–42 to –58.6 V range) with a maximum current capacity of up to 150 A, ensuring stable and efficient operation even under heavy load. An optional Rectiverter module can be added to deliver 230 Vac output (2400 W / 3000 VA), offering AC backup functionality with just +1U additional height.
