The ZTE ZXDU58 B900 is an enterprise-grade -48V floor-standing indoor telecom DC power system engineered to deliver up to 900A of high-reliability output power with hot-pluggable high-efficiency rectifiers and intelligent dual-stage Low Voltage Disconnect (LLVD/BLVD) battery management.
Need to confirm a model, specification, or project configuration? Our team can follow up by email or phone.
The ZXDU58 B900 is an integrated DC power plant comprising three-phase AC distribution, parallel rectifier module slots, a central supervisory unit (CSU), and multi-circuit DC breakers. It operates as the primary source of stable -48VDC power for carrier-grade network equipment while providing comprehensive battery charge/discharge control.
Eliminates power continuity loss caused by severe AC grid fluctuations, resolves online expansion risks via robust live hot-plug rectifiers, and prevents irreversible battery bank deep-discharge damage through programmable tiered load shedding.
Carrier core central offices, large mobile transmission aggregation hubs, metro edge data facilities, and railway signaling telecom rooms.
