Vertiv AS4D0NCXGNNXLKB LIEBERT APS 20kVA Uninterruptible Power Supply

Ensure continuous uptime for mission-critical environments with the Vertiv Liebert APS uninterruptible power supply (UPS). Designed as a modular power solution for 5–20 kVA N+1 applications, the AS4D0NCXGNNXLKB model delivers scalable, redundant power that grows with your load — ideal for data centers, security and surveillance systems, monitoring stations, and IT closets. By supporting up to 20kVA capacity in an N+1 configuration, the Liebert APS reduces single-point failure risk and enables tool-free, hot-swappable maintenance to minimize operational disruption.

Beyond raw capacity, this Vertiv UPS lowers total cost of ownership through modular servicing and efficient power management, while offering flexible rack/tower deployment and integration with networked monitoring for proactive alerts. The solution is backed by a 2-year limited warranty and Vertiv’s global support network, giving you confidence in long-term availability and serviceability. For organizations that require resilient power for cameras, access control, servers or critical networking equipment, the Liebert APS provides a future-proof foundation.
