The LPR48-300-IP67 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. The LPR48- 300-IP67 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-IP67 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.
Line powering enables use of the existing centralized power node backup; eliminating the need at the remote site for AC utility or battery backup. This reduces installation and operating expenses, and provides flexibility related to site selection for the installation of the remote communication equipment.
Power holdup capabilities are incorporated into the LPR48-300-IP67 to provide at least 200 milliseconds of backup for a 300W load. The holdup prevents potential lengthy customer communication outages due to delayed remote node resetting (caused by line surges), ensuring maximum network reliability.
