CRITICAL POWER

48VDC ESB Series Telecom Rectifier System for Telecom Base Station

Reliable on-site power sources are necessary for the continuous operation of telecommunication systems. Cellular towers and repeaters require constant power to ensure network stability, and maintaining and refueling a generator is expensive, inefficient, and time-consuming. So, the ESB series solar power telecom base station can provide a stable -48VDC power supply to the site, avoiding power outages and maintenance.
