Eltek by Powerbox Flatpack S 9kW 2U Powercore

The Eltek by Powerbox Flatpack S 9kW 2U Powercore is a high-density, pre-configured power system engineered for mission-critical reliability in telecom, industrial, and public safety applications. Delivering up to 9 kW of DC power in a compact 2U form factor, it’s ideal for projects that demand robust performance.

This 2U PowerCore system houses 5 Flatpack S HE rectifier modules (48 V / 1000W or 1800W each, not supplied) and includes a Smartpack S controller for system supervision and remote monitoring. It features flexible AC input (100 – 250 Vac, 45–66 Hz), dual 80 A battery breakers, and multiple load distribution points (2 × 80 A + 10 × 30 A). The Powercore delivers a nominal -48 V DC output (-42 to -58.6 V range) with up to 150 A total output current, providing efficient and reliable power in a compact footprint.

An optional Rectiverter module can be added to provide 230 Vac output (2400 W / 3000 VA), offering true AC backup capability with only +1 U additional height.
