Read MoreThe Eltek by Powerbox Flatpack S9kW 6U Powercore with DC/DC Shelf and Solar is a high-capacity, modular DC power system designed for mission-critical telecom, industrial, and security applications. It’s the ideal choice for large-scale projects requiring reliable and efficient DC power.
This 6U PowerCore system houses 5 × Flatpack S HE Rectifier Modules and provides flexible system expansion through its modular architecture. It delivers a nominal –48 V DC output (–42 to –58.6 V range) with a maximum current capacity of up to 150A, enabling up to 9kW total output power depending on configuration.
An optional Rectiverter module can be added to provide 230 Vac output (2400 W / 3000 VA), enabling true AC backup capability with only +1 U of additional height.
