Product Overview
The Vertiv R48-1000E and R48-1000E3 belong to the classic eSure series high-density rectifiers developed by former Emerson. Designed for Vertiv NetSure 2100 and other embedded telecom power systems, this 1000W constant power module adopts patented switching technology and advanced DSP digital processing chip for stable operation. It supports 120V & 200~250VAC mainstream AC input, and converts AC power into adjustable -42VDC ~ -58VDC standard telecom voltage. With high power density up to 45 W/in³ and only 152mm depth, it perfectly fits short-depth racks and compact outdoor enclosures where regular modules cannot be installed. The peak efficiency reaches over 95% to cut daily power consumption. Equipped with hot-swap function and CAN bus communication interface, it supports online replacement and multi-module parallel operation for capacity expansion. It is widely used in 5G small cells, outdoor unmanned cabinets, mini data centers and low-power telecom station renovation projects.
