Vertiv Rpdu Monitored Unit Level EC 22.0KW Variable Power Configuration Horizontal - VP4UV2A1

Vertiv VP4UV2A1 Monitored 3-Phase Rack PDU, 22kW, 24-Outlet, 2U Horizontal

Overview

The Vertiv VP4UV2A1 is a 22kW, three-phase monitored rack PDU designed for high-density data center rows, colocation deployments, and enterprise machine rooms where you need granular current and power visibility at the outlet group level without adding per-outlet switching overhead. Horizontal 2U mounting keeps the unit out of vertical cable runs while preserving U-space on adjacent equipment. If you're speccing power distribution for a rack PDU deployment and need protocol depth — SNMP v3, RADIUS, TACACS+, Modbus TCP — this unit covers the enterprise checklist.

The VP4UV2A1 delivers monitored-class intelligence: real-time current, voltage, and power readings accessible over the network, without the added cost and complexity of switched outlets. That tradeoff is deliberate — monitored PDUs are the right fit when visibility drives your requirement rather than remote load cycling.

Key Features

• 22kW Maximum Power, 63A Input: At 22,000W maximum draw across three phases, this unit is sized for fully loaded high-density racks. The 63A maximum input current accommodates heavy compute and storage loads without nuisance tripping — relevant in GPU server rows where instantaneous draw spikes are common.
• 24 AC Outlets — Mixed C13/C19 Configuration: The combination of IEC C13 and C19 receptacles on a single PDU eliminates the need for stacked single-type units. C19 ports handle high-draw server PSUs and UPS connections directly; C13 ports cover standard 1U servers, switches, and KVM gear. Verify your specific outlet count per type against the VP4UV2A1 configuration sheet before ordering.
• Monitored Current, Voltage, and Power: Per-phase monitoring surfaces the data your DCIM or SNMP poller needs to detect phase imbalance before it becomes a tripped breaker. Catching a 15% imbalance early on a three-phase feed is far cheaper than an unplanned outage during peak load.
• LCD Display: Local readings via the onboard LCD mean a technician can confirm load without a laptop or network session — useful during initial commissioning or when troubleshooting a noisy SNMP trap at 2am.
• Dual RJ-45 Ethernet Ports: Two network ports support daisy-chain networking between multiple PDUs on the same rack or row, reducing the number of switch ports consumed. Combined with the native daisy-chain capability, you can string units together under a single IP block while maintaining per-unit monitoring.
• Enterprise Protocol Stack: SNMP v1/v2c/v3, HTTPS, SSH, LDAP, RADIUS, TACACS+, Modbus TCP, NTP, Syslog, and RSTP in a single firmware build means this PDU integrates with existing authentication infrastructure (Active Directory via LDAP, RADIUS-based AAA) and fits into automated DCIM polling without custom middleware.
• Over-Current Protection: Built-in over-current protection guards connected equipment from load faults propagating across the PDU — a baseline requirement for any production data center installation.
• 50/60 Hz Compatibility: Accepts both 50 Hz and 60 Hz input frequency, which matters if the same SKU needs to deploy across North American and European facilities under a standardized procurement contract.
• 2U Horizontal Form Factor, Black: The horizontal 2U profile mounts cleanly at the top or bottom of a standard rack. Black chassis blends with industry-standard rack equipment — no visible mismatch in mixed-vendor rows.
• Reset Button: Hardware reset capability provides an out-of-band recovery path if a firmware update or misconfiguration renders the management interface inaccessible — a small but operationally significant feature when the PDU is in a remote colo cage.
• Compliance: CE, UL, cUL, UKCA, RoHS, FCC: Multi-jurisdiction certification (CE for EU, UL/cUL for North America, UKCA for UK post-Brexit, RoHS for restricted substances) allows the same model number to be deployed globally. FCC certification confirms it won't create RF interference issues in mixed-equipment environments.

Integration and Compatibility

The VP4UV2A1 integrates with any SNMP-capable DCIM platform, NMS, or monitoring stack — Vertiv's own Trellis, Schneider EcoStruxure, Nlyte, Sunbird dcTrack, and open-source tools like Zabbix or Prometheus via SNMP exporter all work without custom drivers. LDAP/RADIUS/TACACS+ authentication means user access management folds into your existing identity infrastructure rather than maintaining a separate local user database per PDU. Modbus TCP support is specifically relevant for BMS (Building Management System) integrations common in larger colo and enterprise facilities. Explore the full Vertiv power distribution catalog for compatible accessories, input cord options, and higher-density variants. For overall rack power planning, a three-phase PDU selection guide can help match input cord, breaker rating, and outlet mix to your specific rack load profile. Pair this unit with a compatible managed network switch if you're provisioning the dual Ethernet daisy chain across a full row of racks.

Frequently Asked Questions

Q: What outlet types and how many are on the VP4UV2A1?

A: The VP4UV2A1 has 24 AC outlets total, using a mix of IEC C13 and C19 coupler types. The C19 receptacles handle high-draw server and UPS connections; C13 covers standard rack equipment. Confirm the exact per-type split in the Vertiv configuration sheet for this SKU before finalizing your rack cabling plan.

Q: What monitoring protocols does the VP4UV2A1 support?

A: The unit supports SNMP v1, v2c, and v3; HTTPS; SSH; LDAP; RADIUS; TACACS+; Modbus TCP; NTP; Syslog; DHCP; IPv4; IPv6; and RSTP. This covers integration with enterprise DCIM platforms, NMS tools, and BMS systems without requiring additional middleware.

Q: Can multiple VP4UV2A1 units be daisy-chained together?

A: Yes. The VP4UV2A1 supports daisy chaining via its dual RJ-45 Ethernet ports, which reduces switch port consumption when deploying multiple PDUs in the same rack row. Each unit retains individual monitoring data accessible through the daisy chain network topology.

Q: What is the maximum input current and power rating of the VP4UV2A1?

A: Maximum input current is 63A and maximum power is 22,000W (22kW). This is a three-phase unit operating at 50 or 60 Hz, sized for high-density compute and storage rack loads.

Q: What certifications does the VP4UV2A1 carry?

A: The VP4UV2A1 is certified to CE, UL, cUL, UKCA, RoHS, and FCC standards. This multi-jurisdiction compliance supports deployment in North American, European, and UK data center facilities under a single SKU.

Q: Is there local display capability on the VP4UV2A1?

A: Yes. The unit includes an onboard LCD display for local current, voltage, and power readings without requiring a network connection — useful during commissioning or when network access to the management interface is unavailable.
