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.
The Line Power Systems is designed to remotely power -48VDC network equipment reliably using +/- 190VDC over existing copper lines deployed between central offices and remote outside plant (OSP) cabinets. 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 Compact Power Line platform is designed to provide highly reliable DC power for -48V distributed power architectures. A single shelf configuration provides up to 11kW of -48VDC output power within 1U height and mounts in 19-inch or 23-inch wide frames. The CPL product platform is easily expandable for future growth. CPL is a reliable DC power solution for mission critical enterprise and telecommunications network equipment.
The Slimline Power System provides advanced controller features in a compact, cost-efficient footprint. The SPS shelf is 1.75" high, 10.3" deep, and mounts in 19-inch or 23-inch wide frames with three power slots for rectifiers and distribution. The Pulsar Edge controller has Ethernet connectivity to facilitate remote network management to monitor and control rectifiers, batteries, and distribution. SPS is a reliable DC power solution where system height and depth are restricted.
Small Power Plants provide up to 3000 Watts of power, or 60 amps, at 48VDC. These systems are rack mountable either in a 19-inch or 23-inch rack configuration, only taking up 1RU of shelf capacity (approximately 1.75in). The power plants are lightweight, only having a depth of 10.3 inches (26.2 cm), and have an efficiency rating of up to 95% depending on the load size.
