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.
