What this product is
What this product is
The Eltek 268035 is an industrial 19-inch 1U high-density Flatpack2 4AC HC power shelf designed for mission-critical telecom and HVDC power systems. It features 4 dedicated AC input feeds and accommodates up to 4 Flatpack2 HE rectifiers, delivering up to 12kW / 240A DC power across -48V or HVDC bus architectures, with CAN-bus integration for Smartpack controllers.
What problem it solves
The Eltek 268035 Flatpack2 4AC HC power shelf establishes an industry-leading benchmark for ultra-compact DC power distribution. Built with a standard 19-inch 1U profile, it integrates low-impedance heavy-duty copper DC busbars and 4 individual AC feed terminals, providing complete physical isolation against AC phase cross-faults. Engineered specifically for Eltek Flatpack2 HE (High Efficiency) rectifiers, the shelf achieves full-system conversion efficiency above 96.5%, dramatically reducing operational thermal footprint. The power shelf features true blind-mate hot-swappable architecture, allowing non-disruptive rectifier insertion and extraction under live loads without DC bus voltage dips or arcing. A dedicated controller bay accommodates Smartpack2 or Smartpack S master modules, interfacing through CAN-bus networks and delivering SNMP, Modbus, and secure HTTPS remote management. Operating reliably across -40°C to +75°C via front-to-back straight-through airflow, the 268035 is built for telecom base stations, modular HVDC distribution, and mission-critical power grids.
