Product Overview
The Vertiv R24-2200 (Former Emerson eSure Series) is professional high-density digital switching rectifier specially designed for 24VDC telecom, railway and industrial embedded power systems. Rated max 75A/2200W(2175W nominal) output at adjustable 21.6~28.8VDC, it converts wide-range 85~290VAC single-phase alternating current into stable 24V standard industrial & telecom voltage. Adopts advanced DSP full digital control and active PFC topology, full-load PF≥0.99 and rated efficiency ≥92%. Standard drawer hot-swap plug structure supports live maintenance without system power cut; intelligent automatic current sharing for multi-module parallel expansion, built-in monitoring communication interface for remote parameter setup, ideal for railway signal cabinet, industrial automation and 24V telecom station power renovation projects.
Key Features
Ultra-wide AC input:85~290VAC(45~65Hz, nominal200~250VAC), stable for unstable grid and diesel generator power supply
