What this product is

What this product is

The DUM4850H3 is a standardized single-cabinet DC power plant conforming to international telecom standards. It integrates Class C surge protective devices (SPD), AC circuit breakers, hot-pluggable switch-mode rectifier slots in an N+1/N+2 architecture, and fully isolated DC distribution branches. An onboard central controller monitors bus voltage, load current, battery SOC/SOH, and module telemetry, coordinating dynamic load sharing and remote network communications via RS485/CAN/SNMP protocols.

What problem it solves

It resolves critical operational risks such as grid-induced electrical transients, partial module failures cascading into full system blackouts, and permanent battery damage caused by deep over-discharge. Its integrated footprint eliminates cumbersome on-site inter-cabinet cabling, drastically reducing installation lead times, footprint constraints, and engineering overhead in space-limited equipment rooms.

Who and where it is for

Ideal for mobile operator regional aggregation hubs, core switching centers, enterprise private telecommunication nodes, metro rail transit communication rooms, and mission-critical industrial automation DC networks.
