The Vertiv BMK1115601-006 is a telecom-grade -48VDC embedded switched-mode power supply (SMPS) subrack system integrating high-efficiency rectifiers, intelligent DC distribution, and supervisory control architecture.
Need to confirm a model, specification, or project configuration? Our team can follow up by email or phone.
Engineered as an integral component of the Vertiv NetSure power platform, this subrack integrates modular rectifier slots, advanced supervisory controller wiring, AC surge protection, and dual contactor-driven DC distribution panels. It delivers continuous, filtered -48V DC power directly to telecommunication transport nodes and wireless access networks.
Resolves erratic utility grid fluctuations and site blackout threats by pairing wide input tolerances with deterministic multi-stage battery management, preventing destructive battery deep-discharge events and uncoordinated network dropouts.
Telecom operator 4G/5G macro sites, optical transport aggregate nodes, micro-datacenter DC distribution rows, tower shelter cabinets, and mission-critical SCADA networks.
