Vertiv UI30004L 3-Phase 30A Monitored Rack PDU

The Vertiv UI30004L is a three-phase, 30A rack power distribution unit rated for 230/400V environments, delivering 30 C13 outlets with input- and per-phase power monitoring. Designed for high-density data center rows and critical infrastructure racks where unbalanced phase loading is a real operational risk, the UI30004L gives facilities teams the visibility to catch problems before they cause downtime — without deploying a separate monitoring appliance.

Overview

Part of the Vertiv Liebert rPDU line, the UI30004L targets three-phase deployments in enterprise data halls, colocation facilities, and telecom equipment rooms running 230/400V three-phase power infrastructure. The unit connects via a 3P+N+E plug (IP44-rated for wet-location and industrial panel compatibility) with a 10 ft / 3 m input cord — long enough to reach overhead busway or raised-floor PDU drops without extension hardware in most standard rack configurations. The black powder-coat finish matches standard 19-inch rack aesthetics and indicates a unit specced for permanent infrastructure installation rather than temporary or lab use.

Key Features

• 30 C13 Outlets at 30A / 230/400V Three-Phase: Thirty IEC C13 receptacles across a three-phase 30A feed means you can load a fully populated 42U rack of 1U servers without outlet conflicts. At 230/400V three-phase, you're pulling from all three legs — critical for keeping phase currents balanced and staying well inside breaker ratings. If you're still deploying single-phase PDUs in three-phase rooms, the per-leg headroom available here is a meaningful operational upgrade.
• Input and Per-Phase Power Monitoring: The UI30004L measures power at both the input (total draw) and per-phase level, plus circuit/breaker current monitoring. That per-phase granularity is the key spec: you can see exactly which leg is running hot before it trips a breaker — a critical capability in colo environments where tenants share a three-phase feed or where mixed server generations create uneven load profiles.
• Local High-Visibility LED Display: A front-panel LED readout provides at-a-glance current readings without requiring a network connection or software login. During physical maintenance windows or power events, local visibility matters — you don't want technicians running to a laptop to confirm load before swapping a device.
• Daisy-Chain Ethernet Connectivity: Rather than consuming a network switch port per PDU, the UI30004L supports Ethernet daisy-chaining. In high-density rows with four to eight PDUs, this can eliminate the need for an additional access switch just for PDU management — a real cost and cabling reduction in colocation or edge deployments.
• Optional Remote Environmental Sensors: The rPDU supports optional remote sensor modules for temperature and humidity monitoring. For facilities that need to demonstrate environmental SLA compliance (ASHRAE A1/A2 envelopes, for example), adding sensors to the PDU chain eliminates a separate sensor infrastructure purchase.
• 3P+N+E (IP44) Plug: The IP44-rated plug is rated for splash-proof industrial and data center panel connections. This matters in raised-floor environments where water ingress under the floor is a code consideration, and in industrial or edge sites where the panel connection may not be in a fully enclosed cabinet.
• 10 ft / 3 m Input Cord: A 3-meter cord reaches overhead cable trays or floor-level PDU drops in standard 600mm-deep aisles without requiring a cord extension or custom order. Verify your specific rack-to-panel distance before ordering, particularly in non-standard aisle configurations.
• Black Powder-Coat Finish: Consistent with standard rack infrastructure — blends with both open-frame and enclosed rack environments and holds up to repeated equipment swaps without chipping or oxidizing the way bare metal finishes do in humid facilities.

Integration and Compatibility

The UI30004L is designed for integration into Vertiv's broader rack PDU management ecosystem. The daisy-chain Ethernet architecture means a single IP address and network drop can serve an entire row of rPDUs — consult Vertiv's rPDU management software or your existing DCIM platform for supported polling intervals and alert configurations. The C13 outlet format is compatible with standard server, storage, and network equipment IEC C14 power inputs; verify that any high-draw devices requiring C19 receptacles are homed to a separate PDU or a mixed-outlet variant. For racks running a mix of UPS systems and PDUs, the per-phase monitoring data from the UI30004L can feed into a DCIM dashboard to give a complete power chain view from utility input to device outlet. Pair with a managed PoE switch or dedicated OOB management switch for the Ethernet daisy-chain segment to keep PDU management traffic isolated from production networks. Review Vertiv's rack power distribution selection for alternate outlet configurations and amperage ratings if your load profile differs.

Frequently Asked Questions

Q: What outlet type does the UI30004L use, and is it compatible with standard server power supplies?

A: The UI30004L provides 30 IEC C13 outlets. Standard 1U and 2U servers, switches, and storage arrays with IEC C14 power inputs connect directly — no adapters needed. Devices requiring C19 receptacles (typically high-draw servers above 16A per outlet) are not compatible with this unit's outlet format.

Q: What input plug does the UI30004L use, and what panel connection does it require?

A: The UI30004L uses a 3P+N+E plug rated IP44. This is a five-wire three-phase connector common in European and international data center panel installations. Verify your facility's panel type before ordering — North American NEMA L21-30 or other regional plug formats are not compatible without a rewire or adapter.

Q: Can multiple UI30004L units share a single network connection for management?

A: Yes. The UI30004L supports daisy-chain Ethernet, allowing multiple PDUs in a row to share a single upstream network port. This reduces switch port consumption and simplifies cabling in high-density PDU deployments.

Q: Does the UI30004L support environmental monitoring?

A: Optional remote sensors can be added to the UI30004L for temperature and humidity monitoring. These are not included in the base unit — contact your procurement team to specify the appropriate Vertiv sensor accessories for your compliance requirements.

Q: What is the input voltage and current rating of the UI30004L?

A: The UI30004L is rated for 230/400V three-phase input at 30A. This is a standard three-phase rating for European and international data center infrastructure — confirm your facility's available phase voltage before installation.

Q: What monitoring granularity does the UI30004L provide?

A: The unit monitors at three levels: total input power, per-phase power (covering all three legs individually), and per-circuit/breaker current. This granularity lets operations teams identify phase imbalance, overcurrent conditions, and circuit-level load anomalies without additional monitoring hardware.

The UI30004L is a three-phase monitored rPDU that solves a specific and common data center operations problem: knowing which phase is approaching its limit before the breaker opens. The per-phase monitoring on this unit gives you granular current readings on all three legs independently — critical in mixed-generation server environments where phase imbalance is a routine issue, not an edge case.

Technical Highlights:

• Per-Phase + Circuit/Breaker Monitoring: Three-level monitoring (input, per-phase, per-breaker) means you can pinpoint load anomalies to the specific circuit, not just the whole PDU — the difference between a five-minute fix and a 45-minute troubleshooting session during a midnight incident.
• 30 C13 Outlets / 30A Three-Phase: Thirty outlets across a 30A three-phase feed at 230/400V. In a typical 42U rack of dual-PSU 1U servers (each drawing 3–4A per PSU), you have headroom to fully populate without outlet conflicts — assuming balanced phase loading, which the monitoring helps you maintain.
• Daisy-Chain Ethernet: A single network drop can manage an entire row of rPDUs. In a 10-rack row with two PDUs per rack, that's potentially 19 switch ports saved — meaningful in colocation environments where every managed port has a monthly cost.

Deployment Considerations:

• The 3P+N+E (IP44) plug is specific to international three-phase panel standards — confirm your facility's panel type matches before the unit ships. A plug mismatch on delivery day in a live data hall is an expensive problem.
• The 30 C13 outlets do not include any C19 receptacles. If your rack includes high-density compute (blade chassis, high-core-count GPU servers) that require C19 inputs, plan for a mixed-outlet PDU or a separate C19 unit for those devices.

The UI30004L is the right call for European or international colocation deployments running 230/400V three-phase infrastructure where per-phase load visibility and outlet density are the primary requirements — particularly in rows where tenant SLAs make unplanned breaker trips unacceptable.
