Uninterruptible Power Supply (UPS)
Maintenance
Regular scheduled maintenance is always recommended. Thorough inspection that includes diagnostics will help ensure optimum performance when you need it most.
Tips
- Perform recommended maintenance (click here for Odyssey Power maintenance plans).
- Perform load test annually to help ensure reliability of system.
- Maintain accurate service records (click here for a sample of our Client Information Center).
- Always maintain adequate clearance for service accessibility.
Life Expectancy
If a UPS is well maintained from the date commissioned, in most cases you can expect roughly 10 to 13 years of high reliability, and some manufacturers have claimed 20 years.
The most common parts typically replaced during the life of a UPS are batteries, electrolytic DC capacitors, oil-filled AC capacitors, fans and fuses.
Tips
- At some point, the UPS manufacturer will discontinue replacement parts for your UPS. Make sure your service provider has a stock of replacement parts in the event of an equipment failure. Of course, Odyssey Power will keep you informed of any discontinued parts from the manufacturer.
- The life of a UPS can be prolonged through continued repairs and parts replacement, but this approach becomes less and less cost effective and will eventually result in an outdated and unreliable system.
Sizing
When sizing a UPS and battery system, we recommend considering the current load and projected future load consumption.
Tips
- Add up all the connected load consumption based on the amperes or watts. Include any future growth expansion within the next couple of years.
- Calculate for no more than 60% load on the UPS.
- Figure out the desired backup runtime needed from the battery system in the event of a power outage. If you plan to install a generator and ATS for emergency backup, battery runtime may be reduced since the generator would be supporting the load within 5-30 seconds of a power outage.
- If there are no plans for generator backup, then an hour of runtime based on full load capacity of the UPS may be sufficient, as utility company outages are typically restored within that time.
