Eltek DC Power System — Flatpack S 1U & Flatpack2 8kW

Eltek provides industry-standard modular solutions for -48V DC power systems. Flatpack S 1U: complete system in a single chassis (controller + rectifiers + battery/load distribution), only 262mm depth, 40A–100A output. Flatpack2 8kW: 2000W modules, 8kW capacity with 4 modules, N+1 redundancy, 96% efficiency. Both systems equipped with Smartpack S controller, hot-swappable modules and Ethernet/SNMP monitoring. For telecom base stations, server rooms, fiber and broadband infrastructure.

Scope / deliverables

  • Eltek Flatpack S 1U — compact complete system: Smartpack S controller + Flatpack S 1800W rectifiers + battery distribution + load distribution, all in a single 1U 19" chassis; only 262mm system depth → fits in 300mm minimum cabinets
  • Flatpack S 2R model: 1 controller + 2 rectifiers = max 40A / ~3.6kW output; 230VAC 1-phase or 2×1-phase input; front load: 4×30A MCB or 7×15A fuse; optional 7×30A MCB drawer (LVLD)
  • Flatpack S 3R model: 1 controller + 3 rectifiers = max 100A / ~5.4kW output; 230VAC 3-phase (Δ/Y) or 400VAC 3-phase; rear load 2×80A; battery 2×80A breakers (M6 cable lug)
  • Eltek Flatpack2 8kW — modular industry standard: Flatpack2 48V/2000W HE modules (48V, 41.7A/module); 4 modules in parallel = 8kW total DC capacity; add 5th module for N+1 redundancy
  • Flatpack2 rectifier module specs: 2000W output, 48V DC (adjustable 42–58V), >96% efficiency, power factor >0.99, input 100–340VAC wide range, 45–66Hz, -40°C~+65°C, 2.6 kg, 40.5×112×254mm
  • Smartpack S controller — both systems: Ethernet (TCP/IP), SNMP v1/v2c/v3, HTTP/HTTPS web UI, Modbus TCP; 6× digital I/O; battery charge management and temperature compensation; LVLD (Low Voltage Load Disconnect); battery testing and health monitoring; hot-swappable
  • Applications: mobile/wireless telecom (LTE/4G/5G, WiMAX, DAS, microwave), fixed telecom (FTTX, fiber, broadband), data center DC power, industrial control infrastructure
  • Design standards: UL 60950-1, EN 60950-1 (electrical safety); ETSI EN 300 386, EN 61000-6-1/2/3/4 (EMC); ETSI EN 300 019-2-1/2/3 (environmental)
  • Promark: DC power system sizing, installation, commissioning, SNMP/NMS integration, battery integration, spare module supply and periodic maintenance
