Huawei PMU11A Genuine Telecom Hardware Shot 1
HuaweiModel: PMU11A

Huawei PMU11A Power System Environment & Battery Data Acquisition Monitoring Module (CAN/RS485)

The Huawei PMU11A is a carrier-grade power environment and battery data acquisition module engineered for -48V DC telecom power systems. It provides precision analog and digital sampling, leveraging dual CAN bus and RS485 communication interfaces to transmit battery midpoint voltage, charge/discharge currents, ambient metrics, and dry-contact states to the system controller.

What this product is

What this product is

Architecturally, the PMU11A serves as the peripheral data acquisition node within Huawei telecom power enclosures (such as the TP48 series and APM30 cabinets). It integrates multi-channel precision analog-to-digital converters (ADCs), optocoupler-isolated digital inputs (dry contacts), precision NTC temperature sensor front-ends, and galvanically isolated transceivers complying with IEC 60950-1 and ETSI EN 300 386 carrier-grade standards.

What problem it solves

It eliminates the risk of catastrophic battery bank thermal runaway, unmonitored cell imbalance, and premature battery degradation by providing real-time data for automated float/boost charge control and temperature compensation, while preventing blind spots caused by unmonitored cabinet doors, flooding, or surge protection failures.

Who and where it is for

Tailored for Huawei NetEco-managed -48V DC power frameworks, APM30/APM5930 outdoor telecom cabinets, cellular 4G/5G macro and micro base stations, optical transmission nodes, and enterprise remote edge sites.
