ELTEK Flatpack S 48V 1U
The ELTEK Flatpack S 48V 1U is a high-efficiency (HE), ultra-compact DC power system designed specifically for space-constrained telecommunications environments. Its shallow design makes it an ideal choice for 19″ or 23″ cabinets where depth is limited.
General Description for ELTEK Flatpack S 48V 1U
The Flatpack S 1U system is a complete power solution that integrates rectification, distribution, and advanced monitoring into a single rack unit. It is engineered to meet the increasing power demands of 4G/5G nodes and fiber-to-the-curb (FTTC) applications. The system’s 262 mm (10.3″) depth allows it to fit into almost any standard telecommunications cabinet, making it a preferred “drop-in” replacement for older, less efficient power units.
Key Components for ELTEK Flatpack S 48V 1U
- Rectifiers: Supports Flatpack S HE modules (typically 1000W or 1800W). These are hot-pluggable, allowing for maintenance or scaling without powering down the load.
- Controller: Features the Smartpack S, a compact, hot-pluggable controller providing advanced monitoring, battery management, and Ethernet-based remote access.
- Distribution: Integrated battery and load distribution with various protection options (MCBs or Fuses).

System Configuration Options for ELTEK Flatpack S 48V 1U
The Flatpack S 1U system is typically offered in two main power densities, depending on the number of rectifier slots (R) used:
1. The 2R System (Up to 40A)
Designed for lower power requirements with more space for distribution.
- Load Options:
- Drawer Style: 7 x 30A MCB (with optional Low Voltage Load Disconnect – LVLD).
- Front Access: 4 x 30A MCB.
- Fuse Option: 7 x 15A fuses (front access).
2. The 3R System (Up to 100A)
Designed for higher power density by utilizing three rectifier slots.
- Load Options:
- High Capacity: 2 x 80A MCB (front access) for bulk power distribution.
Why Choose Flatpack S 1U?
- Scalability: Start with one rectifier and add more as your site’s power demand grows.
- Energy Savings: The HE (High Efficiency) technology significantly reduces electricity costs and heat dissipation.
- Remote Management: The Ethernet-enabled Smartpack S controller allows technicians to monitor battery health and system status from any location.
- Compact Footprint: Perfect for “edge” locations, small outdoor enclosures, and crowded street-side cabinets.
Part Number of ELTEK Flatpack S 48V 1U materials
The Eltek Flatpack S 48V 1U power system uses several different part numbers depending on whether you are identifying the individual modules (rectifiers and controllers) or the complete system shelf (2R or 3R configurations).
