APC SMART-UPS VT ISX 20 kVA 208 V | Online UPS, Enterprise

Maintain power continuity for demanding server rooms and network closets with the APC SMART-UPS VT ISX 20 kVA platform. Built for 208 V environments, this online UPS is designed to isolate connected equipment from utility disturbances while supporting critical loads that cannot tolerate downtime. This configuration includes 3 battery modules, a PDU, and startup service, giving infrastructure teams a deployment-ready package instead of a bare chassis. The expandable battery architecture supports growth to 5 modules, allowing runtime planning to scale with workload requirements and recovery objectives. For organizations standardizing on higher-capacity protection, this model fits the gap between smaller rack UPS systems and full facility power infrastructure. It is suited to environments where clean output, predictable transfer behavior, and service-backed commissioning matter as much as raw capacity. The result is a more controlled power layer for virtualization hosts, storage, edge compute, and network aggregation points. Choose this system when the cost of interruption exceeds the cost of engineered protection. The included startup service helps ensure the unit is installed and configured correctly from day one, reducing risk during commissioning and accelerating time to protection.
