Vertiv 18414 - Rpdu Metered Surge

Vertiv 18414 Metered Surge PDU — 20A Single-Phase 10-Outlet Rack Power

Overview

The Vertiv 18414 is a 0U horizontal rackmount power distribution unit designed for single-phase AC distribution in IT equipment racks. With a 20A NEMA L5-20P input, 10 NEMA 5-20R receptacles, and real-time current metering via an LED display, it gives rack administrators live visibility into load draw without requiring a remote management session. For server rooms, network closets, and surveillance equipment racks running 100–120V infrastructure, the 18414 covers the full load budget in a space-efficient 0U form factor that mounts horizontally without consuming a rack unit.

The surge protection built into the 18414 adds a layer of defense against transient voltage spikes — relevant in any rack environment where a connected switch, NVR, or encoder rack could lose configuration or hardware to a voltage event. This is not a UPS replacement, but for environments where clean utility power is the norm and transient protection is the requirement, it hits the right cost-to-protection tradeoff.

Key Features

• 10 NEMA 5-20R Receptacles: Ten 20A-rated outlets means you can fully populate a mixed rack — NVRs, PoE switches, video encoders, KVM units — without daisy-chaining strips. Each outlet accommodates standard NEMA 5-15P plugs as well, giving flexibility across device types.
• 20A NEMA L5-20P Locking Input Plug: The twist-lock L5-20P connector prevents accidental disconnection at the PDU end — a practical requirement when the PDU is installed in a high-density rack where cable pull tension is a real risk. Pair this with a 20A L5-20 circuit breaker at the panel for proper branch-circuit coordination.
• Real-Time Current Metering via LED Display: The front-facing LED shows live amperage draw, so rack administrators can verify load balance before and after adding equipment. No SNMP agent, no network port needed — the reading is local and immediate. If your total draw is creeping toward the 20A maximum, you see it before a breaker trips.
• 0U Horizontal Mounting: Mounts flat in the rack without occupying a rack unit — critical in 1U/2U environments where every unit is spoken for. The horizontal orientation suits standard 19-inch open-frame and enclosed racks equally well.
• 3-Meter Input Cable: The 3m (approximately 9.8 ft) power cord gives enough reach from a floor-level PDU receptacle or wall outlet to a mid-rack installation without requiring an extension — keeps the cable path clean and reduces clutter.
• 100–120V / 50–60Hz Input Range: Operates across the full North American voltage range and both 50Hz and 60Hz utility frequencies. Standard for US deployments; also compatible with 50Hz environments where 120V single-phase is available.
• Surge Protection Included: Transient voltage suppression protects downstream rack equipment from line-borne spikes. For surveillance racks with NVRs storing active footage, even a brief voltage event can corrupt recordings or damage hardware — surge protection at the PDU level is the last line of defense before the devices themselves.
• Power LED Indicator: The power status indicator confirms the PDU is energized at a glance — useful during rack commissioning and after any power restoration event to verify the PDU is online before investigating downstream device issues.
• No Per-Outlet Switching: The 18414 does not include per-outlet on/off switching. All 10 outlets are always live when the PDU is energized. If you need outlet-level remote switching for remote power cycling of hung devices, you'll need a switched or switched+metered PDU variant.

Integration & Compatibility

The 18414 integrates into any standard rack infrastructure running 100–120V single-phase circuits. It is not network-managed and requires no software integration — the LED metering is standalone. For environments that need SNMP monitoring, remote switching, or per-outlet metering, the broader Vertiv PDU lineup includes managed and switched variants that extend on this platform. The NEMA 5-20R receptacles are universally compatible with standard IT equipment power cords, including the C13-to-5-15P and C13-to-5-20P cords common on rack servers, switches, and NVRs.

If your facility uses a UPS with NEMA L5-20R output receptacles, the 18414's locking L5-20P input mates directly without adapters — a clean integration for protected rack environments.

Frequently Asked Questions

Q: What input plug does the Vertiv 18414 use?

A: The 18414 uses a NEMA L5-20P twist-lock plug on a 3-meter input cord. This mates with NEMA L5-20R receptacles found on many UPS units and dedicated 20A PDU circuits.

Q: How many outlets does the 18414 provide, and what type are they?

A: The 18414 provides 10 NEMA 5-20R outlets. These accept both NEMA 5-15P (standard 15A) and NEMA 5-20P (20A) plugs, covering virtually all standard IT equipment power cords.

Q: Does the Vertiv 18414 include remote network management or SNMP support?

A: No. The 18414 is a local-metered PDU with an LED display for current monitoring only. There is no network port, SNMP agent, or remote management capability. For network-managed power distribution, look at Vertiv's switched or managed PDU variants.

Q: Can I remotely switch individual outlets on the 18414?

A: No. The 18414 does not include per-outlet switching. All 10 outlets are energized whenever the PDU has input power. If remote power cycling is required, select a switched PDU from the Vertiv line.

Q: What rack space does the 18414 consume?

A: The 18414 is a 0U PDU that mounts horizontally, consuming no rack unit space. It installs in the standard PDU mounting channel on the side or rear of most 19-inch racks.

Q: What is the maximum load the 18414 can handle?

A: The 18414 is rated for 20A maximum input current at 120V, which corresponds to 2,400W continuous capacity. For safety and NEC compliance, sustained load should not exceed 80% of the rated circuit breaker — effectively 16A or approximately 1,920W continuous on a 20A circuit.

The Vertiv 18414 sits in a specific and underserved spot in rack power planning: you need local current visibility, surge protection, and 10 NEMA 5-20R outlets in a 0U footprint, but you don't want to pay for managed switching you won't use. At 20A on an L5-20P input, the 18414 gives you the full 20A branch circuit budget distributed across 10 devices with live load reading on the LED — no software, no network port, just real-time amperage at the rack face.

Technical Highlights:

• 20A / NEMA L5-20P Input: Locking twist-lock input eliminates accidental disconnection under cable tension — in dense racks where power cord management is imperfect, this is the spec that prevents unplanned outages.
• 10x NEMA 5-20R Outlets: Ten 20A-rated outlets on a single 20A circuit means each device draws proportionally — plan for 80% utilization (16A total) for NEC-compliant continuous operation. Enough outlets to power a full NVR + switch + encoder stack without a second PDU.
• LED Current Metering: Local amperage readout is the right tool for rack commissioning and troubleshooting — verify draw after each device addition, confirm you're not approaching the 20A input threshold before the circuit breaker makes that determination for you.

Deployment Considerations:

• The 3-meter cord works well for rack-to-floor runs but may be short for ceiling-fed circuits — measure your panel-to-rack distance before ordering.
• No outlet-level switching means you cannot remotely reboot a hung NVR or switch through the PDU itself; if remote cycling is part of your operational playbook, this is a hard limitation that requires a switched PDU instead.

The 18414 is a practical fit for surveillance equipment racks in wiring closets or server rooms where the priority is clean power distribution with local load visibility and surge protection — and where a network-managed PDU would be over-engineered for the application.
