APC NetShelter Rack PDU Advanced Metered 7.4kW Single Phase

The APC NetShelter Rack PDU Advanced Metered (APDU9943) is a single-phase, outlet-metered power distribution unit engineered for high-density enterprise rack environments requiring granular power visibility. Built around APC's fourth-generation Network Management Card (NMC4) architecture, it delivers real-time inlet and per-outlet current, voltage, power (kW), and energy (kWh) metering via an integrated local display and over the network through SNMP, Modbus TCP, and REST API interfaces. The 7.4 kW power capacity accommodates standard enterprise compute, storage, and networking loads without requiring three-phase infrastructure, making it a straightforward fit for conventional single-phase branch circuits.

The NMC4 platform provides dual Ethernet ports with a built-in switch for daisy-chain network connectivity, significantly reducing the number of network drops required across a row of racks. The card supports IPv4 and IPv6 simultaneously, TLS 1.3 encrypted management sessions, RADIUS and LDAP authentication, and role-based access control, aligning with enterprise security hardening requirements. Firmware updates and configuration can be performed centrally through APC's EcoStruxure IT platform or third-party DCIM tools via published APIs.

The APDU9943 is designed for deployment in standard 0U vertical or toolless horizontal mounting positions within APC NetShelter and compatible third-party enclosures. Its outlet-level metering enables IT operations teams to track per-device power consumption for capacity planning, chargeback reporting, and PUE optimization. The unit is widely deployed in enterprise data centers, colocation facilities, and server rooms where single-phase power is the prevailing infrastructure standard and detailed power analytics are operationally required.

Ideal for

• Enterprise data center capacity planning: per-outlet kWh metering enables accurate power budgeting and prevents rack oversubscription during hardware refresh cycles.
• Colocation tenant chargeback: outlet-level energy data exportable via API supports automated billing calculations for multi-tenant shared rack environments.
• DCIM integration: REST API and SNMP MIB support allows real-time power telemetry ingestion into EcoStruxure IT, ServiceNow, and third-party data center management platforms.
• Security-hardened IT infrastructure: TLS 1.3, RADIUS/LDAP authentication, and role-based access control satisfy enterprise security policies for network-attached power infrastructure.
• Network cabling reduction in high-density rows: dual Ethernet daisy-chain reduces IP address and switch port consumption across multi-rack deployments.
• Sustainability and PUE reporting: continuous inlet and outlet power data supports mandatory energy reporting, carbon footprint tracking, and green IT initiatives.
