ABB Line Power Systems for DAS are designed to remotely power -48Vdc network equipment reliability using +/- 190Vdc over existing copper lines deployed between head end and remote antennas in your Distributed Antenna System (DAS) sites. This provides power distribution with battery back-up maintained at a central location to avoid costs of deploying and maintaining remote battery strings at OSP cabinet or customer premise locations. Controllers include a display and local access port, and a LAN interface that can be local or network enabled. A single controller can manage up to 24 converter shelves. ABB Line Power Systems ensure reliable network service from your DAS and small cell networks.

New voice, video and data subscriber services can be delivered over fiber optic lines, while the legacy copper lines already deployed in the ground are used to leverage the central office battery backup and generator power sources in the event of an electrical utility grid outage. Applications include triple-play infrastructure, wireless network distributed antenna systems, and FTTN/FTTH fiber infrastructure.

The Line Power Systems modular architecture provides both upstream and downstream converters. Upstream converter shelves are available for both central office applications and OSP cabinets. Upstream power converters take -48Vdc input and convert to +/- 190Vdc output power for distribution over twisted pair copper lines with appropriate input current limits and hold-over. Downstream converter shelves are available for 650 Watt and 1300 Watt applications. Downstream power converters take +/- 190Vdc input over twisted pair copper and convert to -48Vdc to power remote network equipment. This provides power distribution with battery back-up maintained at a central location to avoid costs of deploying and maintaining remote battery strings at OSP cabinet or customer premise locations.
