Vertiv VA6U21A0 Monitored Outlet-Level Rack Transfer Switch PDU

Overview

The Vertiv VA6U21A0 is a single-phase, 0U horizontal rack transfer switch with outlet-level monitoring — built for data center rows and network closets where dual-feed redundancy is the expectation, not a luxury. It accepts a C20 input plug, supports 100–240 V AC at 50/60 Hz, and delivers up to 16A or 20A across six C13 and C19 outlets. The LCD display gives you at-a-glance power metrics without opening a browser, and the onboard Ethernet port ties it into SNMP, HTTPS, and a full suite of enterprise network protocols for centralized power management. This is not a basic metered strip — it is a monitored transfer device designed to keep load running when a source fails.

Key Features

• Outlet-Level Monitoring (Current, Power, Voltage): Every outlet reports actual draw — not just aggregate input. That means you can identify which device is overloading a circuit before it trips, and allocate rack power budget with real data instead of nameplate math.
• Dual-Voltage Input (100–240 V, 50/60 Hz): The VA6U21A0 handles the full commercial voltage range, making it equally deployable in 120 V North American environments and 208 V three-phase-derived single-phase rows. No transformer tap changes, no hardware swaps between sites.
• C20 Input / Mixed C13 + C19 Outlets: The C20 coupler input matches standard PDU whips and in-row power panels. The outlet mix of C13 (typically 1U servers, switches) and C19 (high-density compute, larger UPS loads) means you are not forced to use IEC adapters for power-hungry nodes sharing the same strip.
• LCD Display: Local power readings without SSH or browser access — useful during initial commissioning or when the network is down. Eliminates the guesswork of
