Depot Repair Center

Gruber Power Services operates a state-of-the-art depot repair facility staffed by highly trained technicians specializing in the service and restoration of a wide range of critical power protection equipment.

Our capabilities include component-level repair of modules and subassemblies, UPS fan rebuilding, and battery pack reconditioning—all performed with precision and attention to OEM specifications.

At any given time, a high volume of equipment moves through our Depot Repair Center, which features multiple service bays equipped to handle 480V, 208V, and 120V equipment across both single- and three-phase configurations.

To ensure each unit is fully restored to operational excellence, our facility is outfitted with load banks that simulate real-world Data Center conditions, allowing us to verify performance under demanding loads and exceed original manufacturer benchmarks.

We also maintain a dedicated UPS battery module rebuild division, supported by a variety of charging and diagnostic systems for multiple brands. Unlike typical suppliers, Gruber builds and refurbishes battery packs to order—ensuring customers receive freshly assembled units, not pre-aged inventory that has been sitting on a shelf, degrading in performance and lifespan.

The same Depot also serves as an ongoing training and auditing hub for our Field Engineers, who are regularly cycled through for hands-on skill refinement and certification—ensuring that expertise in the field matches the precision of our in-house operations.

Included in our Depot Service Program

  • Rental Services – Fast Turnaround – Large Stock of Parts – Auto-notify Service Program – Extended UPS Warranties Available
    We also stock many styles, brands, and types of refurbished UPS and power protection equipment available for immediate sale.

  • Service on smaller UPS’s and other power protection equipment may be more cost effective on a “Depot Repair” basis. When combined with our Auto-Notify Service Program™, we take all the guesswork out of your small equipment maintenance program.

  • In the Power Conditioning service industry, a select few companies have the advanced skills required for component level troubleshooting and repair. Service is generally “module swapping”.  Gruber Power technical capabilities include both component level repairs and when expedient, the traditional module swapping approach in the field.

  • Our Depot Repair Service group provides module and sub-assembly repair for many other independent UPS service organizations.
