This is the Refurbished Version.

Each unit is serviced in our professional electronics lab by experienced engineers, ensuring the highest level of reliability and performance.

As a four-decade industry veteran, Gruber Power pioneered the refurbishment of critical power equipment modules like this. Our meticulous rebuild process includes full load bank testing in our UPS Depot Operations, simulating worst-case conditions to validate proper operation under real-world loads.

Our Critical Power Module rebuild process resets the module to factory specifications and optimal performance, prolongs service life, and reduces the risk of unplanned downtime—at a fraction of the cost of a brand-new replacement.

Each power module operates as a fully independent 4 kVA (2.8 kW) unit, incorporating a power factor-corrected rectifier, battery charger, and inverter, along with integrated monitoring and control electronics. Backed by our full 1-Year Warranty, this refreshed power module delivers dependable performance and peace of mind for mission-critical Liebert Nfinity UPS systems.

Both the tested and refurbished options are fully load-bank tested for worst-case peak demand operation and serviced in our professional electronics lab by experienced engineers to ensure top reliability and performance.
