18kW Rated Power Outdoor DC Power System with 96.2% Rectifier Efficiency for 19-inch Standard Rack Outdoor Power Cabinet Deployment
18kW Outdoor DC Power System
,Hot-Swappable Telecom Power Cabinet
,96.2% Efficiency Outdoor Power Cabinet
The Vertiv (formerly E mers on) NetSure 5100 582137100 is a high-performance, outdoor-grade 19-inch rack-mount DC power system with a maximum rated power of up to 18kW at −48VDC. It is purpose-built for outdoor telecom cabinets, 4G/5G macro base stations, hybrid solar off-grid sites, and fixed access network projects.
Equipped with high-efficiency R48-2000e3 eSure rectifiers and an intelligent NCU monitoring unit, this modular power cabinet supports dual voltage (−48VDC / +24VDC) output and multi-stage load shedding. It is specially optimized for harsh outdoor environments and unstable mains or generator power conditions. Featuring a hot-swap modular structure, full remote communication, and solar hybrid access capability, it is widely adopted for global outdoor communication power renovation and new construction projects.
- Standard 19-inch rack structure with a compact, high-density layout customized for outdoor distribution cabinet installation.
- Selectable single-phase AC input: 120/208/240VAC, with an operational range of 85–300VAC for poor grid and generator power conditions.
- Nominal −48VDC adjustable output (42–58VDC), max system capacity 18kW, expandable up to 28.8kW via additional rectifier slots.
- Matched R48-2000e3 high-efficiency rectifier with peak efficiency up to 96.2% and ECO low-load energy-saving mode.
- Wide rectifier working range of −40℃ to +80℃, with no power derating below +65℃ — ideal for outdoor high-temperature sites.
- Hot-swappable rectifier and controller allow spare part replacement without full system power-off.
- Intelligent NCU controller: Ethernet / SNMP V2/V3 / ModBus / RS485 multi-protocol remote monitoring with real-time fault alerts.
- Dual-stage LVD load disconnection, intelligent battery temperature compensation, and capacity calculation to extend battery lifespan.
- Built-in solar/hybrid power access interface to reduce utility grid consumption for off-grid communication stations.
- NEBS Level 3, UL, and CE certified, with complete surge and OVP/OCP/SCP/OTP circuit protection.
