The ZTE CSU401S is a carrier-grade centralized supervisory controller designed for ZXDU series DC power systems, managing AC/DC distribution, rectifiers, and intelligent battery operations.
Need to confirm a model, specification, or project configuration? Our team can follow up by email or phone.
The CSU401S is the central telemetry and control engine for ZTE's medium-to-large telecom DC power systems. Built on a real-time embedded architecture with optically isolated industrial buses and high-precision analog-to-digital converters, it manages clusters of rectifiers, monitors AC/DC power distribution, and reports critical site telemetry upstream to the carrier Network Management System (NMS) via standard IP/SNMP protocols.
Eliminates operational vulnerabilities including uncontrolled battery sulfation due to lack of thermal compensation, uncoordinated rectifier cycling, and costly unguided field visits caused by inadequate remote alarm diagnostics.
5G/4G macro base station cabinets, telecom central offices running ZXDU power racks, metro convergence nodes, and industrial -48V DC infrastructure.
