What this product is
What this product is
The Eltek 268035 is an industrial-grade 19-inch 2U 4-position power subrack engineered for telecom DC power systems, featuring 4 independent AC input terminals and blind-mate backplane to house up to four Flatpack2 HE/SHE rectifier modules, delivering up to 12kW (300A) continuous -48V DC power.
What problem it solves
The Eltek Flatpack2 268035 4AC power subrack serves as the robust structural and electrical foundation for critical telecommunications and network power infrastructures. Engineered in a compact 2U 19-inch standard chassis, this subrack integrates four dedicated blind-mate slots with individual AC input power terminals for each module position, providing complete electrical isolation and flexibility across single-phase or multi-phase power distribution grids. The integrated DC backplane is fabricated with heavy-duty low-impedance tinned copper busbars designed for up to 300A continuous bus current, combined with high-speed digital CAN bus lines for instantaneous plug-and-play communication with Smartpack/Smartpack S supervisory controllers. Supporting Flatpack2 48/2000 HE, 48/3000 HE, and SHE ultra-high-efficiency modules, the subrack facilitates complete system efficiencies exceeding 96.5% while guaranteeing superior mechanical rigidity, thermal dissipation airflow, and harsh environment electrical safety.
