UPS Capacitor Services

It’s not always obvious when a capacitor fails, and this in turn creates a bigger workload on the remaining capacitors. 

It’s important to not wait until your capacitors reach the end of their rated service before you get them replaced. Instead, start getting quotes for replacing the capacitors as they get closer to year seven or eight. 

When should you replace capacitors?

To maximize the performance and reliability of your UPS, be sure to replace capacitors at or near the end of their rated service life. A qualified service engineer can diagnose the condition of the capacitors in the UPS’s and perform a full or partial replacement of capacitor banks.

It is recommended to schedule a full replacement of capacitors used in the primary power-train portion of the UPS around 7-10 years of operation. However, some newer UPS’s may have oil-filled DC capacitors that are rated for the full life of the UPS. At the minimum, an annual inspection will help optimize operation and extend their lifespan.
