Vertiv Rpdu Switched Outlet Level Monitoring EC 50A 208V Delta 14.4KW Vertical (4 - VP7N50A4

Vertiv VP7N50A4 Switched Outlet-Level Monitoring PDU, 50A 208V 3-Phase 48-Outlet Vertical

Overview

The Vertiv VP7N50A4 is a vertical 0U rack PDU engineered for high-density data center and server room environments where remote outlet-level control and real-time power monitoring are non-negotiable. Running at 50A on a 208V delta three-phase circuit, it delivers up to 14.4kW of usable capacity across 48 individually switched outlets — enough headroom for fully populated high-density rows without requiring a second PDU. The 0U vertical form factor installs in the rear cable channel of standard two-post or four-post racks, reclaiming every rack unit for revenue-generating compute or storage.

Unlike basic metered PDUs, the VP7N50A4 gives operators per-outlet switching: you can remotely cycle a hung server, sequence startup loads to avoid inrush spikes, and isolate a failed device without touching the floor. That capability alone justifies the product class in any environment running 24/7 unattended workloads.

Key Features

• 48 Switched Outlets (C13 + C19 Mix): Forty-eight outlets — a combination of C13 and C19 receptacles — handle both standard 1U servers and high-draw devices like GPU nodes, storage controllers, or UPS bypass loads. Per-outlet switching means a locked-up device gets a remote power cycle without dispatching a technician to the data floor.
• 50A / 208V Delta Input, 14.4kW Capacity: At 50A on a 208V three-phase delta feed, the VP7N50A4 provides 14.4kW of total capacity. In a fully loaded high-density row, that's the difference between one PDU covering the row and needing two — a direct impact on cabling costs and branch circuit planning.
• Outlet-Level Current, Voltage, and Power Monitoring: Real-time monitoring at the outlet level — not just at the input — lets you catch load imbalance before it trips a breaker, track per-server power draw for chargeback, and validate that decommissioned equipment actually came off the circuit.
• LCD Display: The onboard LCD gives local technicians an immediate readout of input parameters without logging into the management interface. Useful during commissioning and during incidents when network access may be disrupted.
• Dual RJ-45 Ethernet Ports: Two Ethernet LAN ports support daisy-chaining multiple PDUs under a single IP address, reducing switch port consumption in large deployments. Managing a row of PDUs through one network connection simplifies DCIM integration and firewall rules.
• Comprehensive Protocol Stack: SNMP v1/v2c/v3, HTTPS, SSH, RADIUS, LDAP, TACACS+, NTP, SMTP, Syslog, Modbus TCP, IPv4/IPv6, DHCP, and RSTP are all supported natively. SNMP v3 with authentication and encryption satisfies most enterprise security policy requirements without add-on middleware. Modbus TCP opens a path to building management systems and DCIM platforms that speak industrial protocols.
• Daisy Chain Support: Daisy chaining PDUs reduces the number of switch ports consumed and simplifies IP management in multi-PDU rows. The VP7N50A4 supports this natively, which matters when you're deploying a dozen PDUs across a pod and don't want a dedicated switch port for each.
• 3-Meter Input Cable: The 3m input cable provides enough reach to a top-of-rack or mid-row power distribution panel without extension hardware — a practical detail that eliminates cable management improvisation during install.
• Reset Button + LED Indicators: Onboard reset and LED status indicators give local visibility into controller and outlet state. During a network outage, LEDs confirm whether the PDU controller is functional independent of the management plane.
• 50/60 Hz, 200–240V Input Range: The 200–240V AC input range at 50 or 60 Hz makes the VP7N50A4 deployable in both North American and international data center environments, which matters for organizations with global co-location footprints.
• Vertical 0U Mounting: Zero rack-unit consumption is the right answer in high-density rows. Vertical mounting in the rack's rear cable management channel keeps all 48 outlets accessible without burning 1U or 2U of premium rack space.

Integration and Compatibility

The VP7N50A4's protocol breadth is its integration story. SNMP v3 makes it compatible with any DCIM platform that supports industry-standard MIBs — Nlyte, Sunbird, Vertiv's own Trellis, and most enterprise NMS tools. Modbus TCP extends compatibility to building management systems and legacy industrial monitoring platforms. RADIUS, LDAP, and TACACS+ support means authentication ties directly into existing enterprise directory infrastructure rather than requiring local account management on each PDU. Syslog and SMTP alerting route events into existing SIEM and ticketing workflows.

The dual Ethernet ports and daisy chain capability integrate cleanly with structured network switch deployments where port budgets are tight. For organizations managing large power and UPS infrastructure, the per-outlet Modbus TCP telemetry provides the granular data needed for accurate power usage effectiveness (PUE) reporting.

Vertiv's broader Vertiv power management line includes companion UPS systems, transfer switches, and environmental monitoring that share the same management ecosystem, making the VP7N50A4 a natural component in a Vertiv-standardized data center stack. For teams evaluating rack PDUs across the market, the combination of switched outlet control, three-phase input, and enterprise protocol support positions this unit in the intelligent PDU tier rather than the basic metered segment. Consult a data center power planning guide before sizing branch circuits to confirm that the 50A feed and 14.4kW capacity align with your actual load calculations.

The VP7N50A4 is the unit I reach for when a customer is running high-density three-phase rows and needs granular outlet-level control without adding another management appliance to the stack. The 50A / 208V delta input at 14.4kW means a single PDU covers a fully loaded row in most configurations — and because every one of the 48 outlets is individually switched, you get remote power cycling without a truck roll.

Technical Highlights:

• Per-Outlet Switching across 48 Outlets: C13 and C19 mix covers both 1U server loads and high-draw nodes. Remote cycling a hung device at 2 AM without dispatching staff is the operational case this feature was built for.
• SNMP v3 + Modbus TCP: Most enterprise DCIM and NMS platforms speak SNMP v3 natively. Modbus TCP is the bridge to BMS platforms — critical in co-location and managed hosting environments where the facility team runs a separate monitoring stack from the IT team.
• Daisy Chain via Dual RJ-45 Ports: Linking multiple PDUs under one IP address is not a convenience feature — in a 10-cabinet pod with two PDUs per cabinet, it cuts your management network port consumption in half and simplifies firewall ACL management considerably.

Deployment Considerations:

• The 3m input cable is adequate for most top-of-rack to overhead busway or floor-level panel configurations, but measure your run before ordering — if your panel is floor-mounted on a 52U rack, you may be close to the limit depending on entry point.
• Three-phase delta at 208V means you need a delta-configured branch circuit — confirm with your facilities team before purchase. Wye-configured panels at 208V require a different input configuration, and connecting incorrectly will trip the branch breaker immediately.

The VP7N50A4 is the right specification for managed co-location providers, enterprise data centers standardizing on Vertiv power infrastructure, and high-density HPC or GPU cluster deployments where per-outlet telemetry feeds directly into chargeback or PUE reporting workflows.
