Liebert APS Power Module PM1 Vertiv 5 kVA 4.5 kW | UPS Power Module

Protect uptime where replacement speed matters. The Liebert APS Power Module (PM1) delivers 5 kVA / 4.5 kW of capacity in a modular format designed for Vertiv Liebert APS systems. With 208/120 VAC input support, it fits environments that need dependable power conversion and a straightforward service path when maintaining critical infrastructure. This module is built for teams that value continuity over compromise. Instead of replacing an entire UPS assembly, the PM1 lets you restore or extend capacity at the module level, helping reduce downtime during maintenance events and simplifying lifecycle planning. That matters in server rooms, network closets, and edge deployments where every minute of outage risk has a cost. For procurement and operations teams, the value is in precision. You get a Vertiv-authored power module matched to the APS platform, with the electrical profile expected in enterprise environments. It is a practical choice when you need a replacement component that preserves system compatibility and keeps the power architecture aligned with the original design intent.
