Vertiv Rpdu Monitored Outlet Level EC Residual Current Metering Type B 11.0KW Varia - VP6UU0A1

Vertiv VP6UU0A1 Monitored Vertical PDU with Outlet-Level RCM Type B, 11kW

Overview

The Vertiv VP6UU0A1 is a vertically mounted, outlet-level monitored power distribution unit built for high-density data center racks and critical infrastructure deployments where granular power visibility and residual current detection matter. At 11.0kW capacity across 24 outlets — a mix of C13 and C19 couplers — it handles both standard 1U/2U server loads and high-draw appliances from a single unit. What separates the VP6UU0A1 from basic metered PDUs is the integrated Type B residual current metering (RCM): it detects both AC and DC leakage current, which is a requirement in many European data centers and increasingly specified in North American facilities prioritizing personnel safety and equipment protection. The black vertical form factor is designed to mount in the rear vertical channel of standard 19-inch or 600mm open-frame and enclosed racks, keeping cable management clean and outlet access direct.

Key Features

• 11.0kW / 16A Maximum Current: At 50–60Hz input, this unit supports the power density demands of a fully populated rack of 1U servers or a mix of compute and storage — without requiring a PDU swap as you scale from partial to full rack density.
• 24 Outlets — C13 and C19 Mix: C13 couplers handle the majority of 1U server and networking gear; C19 couplers accommodate high-draw servers, GPU nodes, and storage arrays drawing up to 16A per outlet. Having both types on one PDU eliminates the need for C19-to-C13 adapters, which introduce failure points and violate some data center standards.
• Outlet-Level Monitoring: Rather than just measuring total PDU input, the VP6UU0A1 monitors at each outlet — so you can identify exactly which device is drawing anomalous power, catch a failing PSU before it cascades, and enforce per-rack SLA power budgets with actual data rather than estimates.
• Type B Residual Current Metering (RCM): Type B detects AC, pulsating DC, and smooth DC residual currents — the full spectrum. This is the specification required in most IEC 60364-compliant installations and is increasingly required by risk teams for any rack housing mixed AC/DC power supplies. Simpler Type A detectors miss smooth DC leakage entirely.
• LCD Display: Local status is readable at the rack without requiring network access or a laptop — useful during initial commissioning, troubleshooting under network outage conditions, or in colocation environments where remote access may be restricted.
• Dual RJ-45 Ethernet Ports: Two network interfaces support daisy-chaining PDUs on a single network drop or connecting to redundant management networks — practical in environments where management network uptime is independently managed from production.
• Comprehensive Protocol Stack: SNMP v1/v2c/v3, Modbus TCP, HTTPS, SSH, LDAP, RADIUS, TACACS+, and Syslog are all supported natively. This means the VP6UU0A1 integrates into existing DCIM platforms, network management systems, and SIEM/syslog pipelines without middleware or protocol converters. SNMP v3 specifically provides authenticated and encrypted polling — important if your management VLAN is shared or traverses untrusted segments.
• IPv4 and IPv6 Dual-Stack: Native IPv6 support future-proofs the management plane for facilities already running IPv6-only management networks — a real consideration in large enterprise and carrier environments.
• USB and Serial Ports: The single USB port and RS-232 serial port provide out-of-band console access and local firmware management — critical during network-loss events when IP-based management is unavailable.
• Vertical 1829mm Depth: At 1829mm (roughly 72 inches), the unit spans a full standard 42U rack height in vertical orientation. The 51mm width and 66mm height keep the PDU's rack footprint to a single vertical rail slot, preserving usable U-space for equipment.

Integration and Compatibility

The VP6UU0A1 supports Modbus TCP alongside SNMP v3, which broadens DCIM and BMS integration beyond traditional IT tooling into building management and industrial control environments. LDAP, RADIUS, and TACACS+ authentication integration means user access can be centrally managed and audited through existing enterprise directory infrastructure — no local account sprawl. NTP synchronization ensures log timestamps align with syslog and SIEM event correlation. For facilities running Vertiv's broader infrastructure portfolio, this PDU fits directly into Vertiv's Intelligent Infrastructure management ecosystem. It can also be managed through any standards-based PDU management platform supporting SNMP or Modbus TCP. Organizations evaluating data center power infrastructure should review outlet-count requirements carefully — 24 outlets covers a mid-density rack, but high-density GPU or storage racks may require a higher-outlet-count model in the same family. For facilities requiring a UPS upstream, verify that the upstream UPS output matches the VP6UU0A1's 16A/11kW input ratings before commissioning.

Frequently Asked Questions

Q: What is Type B residual current metering, and why does it matter for my rack?

A: Type B RCM detects AC, pulsating DC, and smooth DC leakage currents — the full range produced by modern switch-mode power supplies and variable-frequency drives. Type A detectors (the more common and cheaper alternative) miss smooth DC leakage entirely. If your rack includes servers with active PFC power supplies or mixed AC/DC architectures, Type B is the correct specification for personnel and equipment protection.

Q: How many outlets does the VP6UU0A1 provide, and what types?

A: The VP6UU0A1 provides 24 AC outlets in a mix of C13 and C19 IEC coupler types. C13 outlets handle standard 1U server and networking gear; C19 outlets accommodate high-draw devices up to 16A. The exact C13/C19 split should be confirmed against the full product datasheet for your specific configuration.

Q: Does the VP6UU0A1 support SNMP v3?

A: Yes. The VP6UU0A1 supports SNMP v1, v2c, and v3. SNMP v3 provides authenticated and encrypted polling, which is required in security-conscious management network environments. It also supports Modbus TCP for integration with DCIM and building management systems.

Q: Can the VP6UU0A1 integrate with LDAP or RADIUS for centralized authentication?

A: Yes. The VP6UU0A1 natively supports LDAP, RADIUS, and TACACS+ for user authentication, allowing access control to be managed through existing enterprise directory infrastructure rather than local device accounts.

Q: What are the physical dimensions and mounting orientation of the VP6UU0A1?

A: The VP6UU0A1 mounts vertically and measures 51mm wide × 66mm tall × 1829mm deep (approximately 72 inches in length), spanning a standard 42U rack in the vertical rear rail position. This preserves all horizontal U-space for equipment.

Q: Does the VP6UU0A1 support IPv6?

A: Yes. The VP6UU0A1 supports both IPv4 and IPv6 on its dual RJ-45 Ethernet management interfaces, making it compatible with facilities running IPv6-only or dual-stack management networks.

The detail I keep coming back to on the VP6UU0A1 is the Type B residual current metering — not because it sounds impressive on a spec sheet, but because I've seen facilities spec Type A and then discover post-installation that their GPU nodes and high-efficiency PSUs generate smooth DC leakage that Type A completely ignores. At 11.0kW and 16A max current, this PDU is sized for real production racks, and pairing that capacity with genuine Type B detection closes a safety gap that a lot of procurement teams don't catch until an auditor flags it.

Technical Highlights:

• 11.0kW / 16A Input: Covers a fully populated mid-density rack without headroom anxiety — and the 50–60Hz acceptance means it deploys across North American and European power infrastructure without input-side modifications.
• Dual RJ-45 Ethernet: Two management interfaces let you daisy-chain to a neighbor PDU on a single switch port, or connect to redundant management VLANs — useful in colo environments where management uptime is contractually separate from production.
• TACACS+ + SNMP v3 + Syslog: This protocol stack hits every checkbox for enterprise security operations: encrypted polling, centralized AAA, and log forwarding to SIEM. Most PDUs ship with SNMP v1/v2c only; v3 with auth+privacy matters when your management VLAN isn't fully isolated.

Deployment Considerations:

• The 1829mm vertical length fits a standard 42U rack cleanly, but verify your rack's vertical PDU channel depth before ordering — some enclosed cabinets have rear-door clearance constraints that conflict with the 66mm profile at the outlet face.
• Outlet-level monitoring generates significantly more SNMP data than input-only metering — confirm your DCIM platform's polling interval and data retention capacity before deploying across a large number of units simultaneously.

This PDU is a strong fit for colocation deployments, financial services data centers, and any facility running a formal power audit program — specifically where Type B RCM compliance is written into the facility standard or lease agreement. It's not the right call for simple power distribution where outlet-level telemetry isn't being consumed; in that scenario, a basic metered PDU will cost less and deliver what's actually needed.
