Description
Protect mission-critical loads while saving valuable floor space with the APC Smart-UPS VT SUVTR20KF3B5S. This rack-mounted, three-phase UPS delivers 20 kVA / 16 kW of double-conversion online power in a single 42U-high enclosure that also houses an integrated PDU, hot-swappable power and battery modules, and a Network Management Card 2 with environmental monitoring. Three VRLA battery modules are pre-installed—providing about 11 minutes at full 16 kW load—and you can add two more to extend runtime as your needs grow. Soft-start circuitry reduces generator and wiring requirements, while built-in static and maintenance bypasses enable zero-downtime servicing. Ideal for small data centers, regional offices, retail hubs, and densely packed server rooms, Smart-UPS VT keeps you online, efficient, and in control.
