Alpha LPR48-300

The LPR48-300 is a compact, sealed, standalone, line powered down-converter unit designed for remote line powering applications using ±190VDC (RFT-V circuit) over twisted copper pairs.

select a product's specifications tab

The LPR48-300 line powered down-converter contains four isolated down-converter circuits to convert the input from four (4) twisted copper pairs and provide up to 300W at 48VDC to remote telecommunication equipment.

Applications include powering mini-DSLAM’s (sealed DSLAM’s), Multi-Dwelling Units (MDU) in Fiber to the Home Networks (FTTH), Distribution Points (FTTdp) as well as outdoor small cells in wireless networks. The LPR48-300 line powered down-converter is sealed to an IP67 rating and may be discreetly deployed virtually anywhere: telecom vaults, pedestals, aerial strands, walls, lamp posts, poles, sides of buildings, bus stops, etc.

  • Remote powering module providing up to 300W output at 48VDC to power remote nodes
  • Designed for installation in underground vaults, poles, walls and strand mount
  • Wide operating temperature range for deployment in harsh OSP environments
  • High reliability sealed and ruggedized design for a long life cycle
  • Built-in holdup to ensure that the remote equipment rides through line surges
