1U 19-inch Embedded DC Power System with 40A/2000W Output and Hot-Swappable Rectifier Subrack

The Vertiv (formerly E merso n) NetSure 212 C23‑S1/S2 is a compact 1U 19-inch subrack embedded switching DC power system, designed for FTTx OLT equipment, small access cabinets, indoor micro base stations, and compact communication equipment rooms. It can be configured with up to two R48‑1000A (20A) or R48‑500A rectifier modules to reach a total maximum output of 40A / 2000W at a nominal −48VDC.

Featuring high-efficiency rectifiers, intelligent monitoring, full front maintenance, and an integrated distribution breaker design, this lightweight power subrack offers a small footprint and easy on-site replacement. It is widely used in global fiber access and compact telecom power renovation projects.
