APC by Schneider Electric APDU11551ME Metered 3-Phase Rack PDU
Overview
The APDU11551ME is a 0U vertical-mount, three-phase metered rack PDU from APC's Netshelter Advanced 11K series, designed for high-density data center and server room deployments running 208V, 3-phase power at up to 100A. At 28,800 VA load capacity and with NMC3 network management card support, this unit gives power administrators real-time branch-circuit-level visibility without adding horizontal rack space — the vertical 0U form factor keeps all 30 outlets accessible along the side rail of standard open-frame or enclosed racks. This is the right PDU when you're powering dense compute or network rows where per-outlet monitoring and remote management from a central NMS matters operationally.
Compatibility
The APDU11551ME is engineered for APC Netshelter SX, SV, and VX series racks, where the vertical mounting channel accommodates the 0U profile. The 30-outlet mix — C13, C15, C19, and C21 couplers — covers server, storage, and high-wattage GPU workloads on a single distribution unit. Input connects via IEC 60309 plug, so the feed circuit must be provisioned with a matching IEC 60309 receptacle or hardwired panel connection rated for 80/100A at 208V 3-phase. NMC3 integration connects this PDU to APC UPS and power management infrastructure, allowing unified management through EcoStruxure IT or compatible DCIM platforms. Works alongside other APC by Schneider Electric rack PDU families for mixed-density rows.
Installation Notes
Operating temperature range is -5°C to 60°C with 5–90% relative humidity (non-condensing) — standard data center environmental envelope. The IP67 rating means the unit is sealed against dust ingress and temporary water immersion, which is relevant if deploying in edge or industrial environments subject to wash-down or condensation. Input frequency accepts 50 or 60 Hz, so the unit deploys globally without derating. Verify your upstream breaker is rated for the full 100A draw before provisioning high-wattage loads across all 30 outlets simultaneously; typical rack enclosure branch-circuit design recommends loading to 80% of rated capacity (80A continuous) for thermal headroom. NMC3 requires a network drop at the PDU location for remote monitoring to function — factor that into switch port planning in dense rows.
