ET48300-A7E412 18kW PV + 12kW Rectifier 12U -48V Hybrid Telecom Power Platform
ET48300-A7E412 18kW PV + 12kW Rectifier 12U -48V Hybrid Telecom Power Platform
The ET48300-A7E412 is a 12U hybrid -48V DC power platform designed for telecom sites using both solar power and AC mains power. It integrates PV input, rectifier modules, battery distribution, load protection, surge protection and intelligent monitoring in one 19-inch rack-mounted system.
This model is suitable for outdoor telecom cabinets, solar base stations, weak-grid sites, off-grid relay stations and battery backup power systems. The front-maintenance design, hot-swappable modules and clear distribution layout make installation, inspection and field replacement easier for telecom engineers.
The system supports 18kW solar input and 12kW rectifier capacity. Six 3kW PV/MPPT modules can work together with three 3kW rectifier modules, while one redundant slot improves system flexibility. The output range is -43V to -58VDC, with rated output at -53.5VDC.
