Understanding Different UPS Topologies

UPS systems are generally arranged by topology of which there are five main groups –

Standby – Best suited for simple backup and supporting less sensitive equipment – allows for protection against sags, surges and outages.

Line-interactive – Best suited for main distribution frame (MDF) and intermediate distribution frame (IDF) communication closets, non-centralized server and network rooms, and general IT – allows for active regulation of voltage either by boosting or decreasing utility power as necessary.

Online – Best suited for mission-critical equipment – allows isolation of equipment from raw utility power, converting from AC to CD and back to AC.

Ferroresonant – Best suited for industrial use such as oil & gas, chemical, utility and heavy industry markets – Allows for a no-break power transfer condition the output and hold energy long enough to cover the time between switching from line power to battery.

Multi-mode – Best suited for companies looking to achieve an optimal balance – UPS can switch between these two modes automatically when it detects problems in the utility power.

Common Causes of UPS Failure

Here are some of the most common faults that can cause your UPS to fail and below you will find a breakdown of how you may reduce risk factors –

 

  • Batteries – Typical lifespan of 3-5 years. This life expectancy can fluctuate greatly depending on placement, ambient temperature, cycling, maintenance, battery chemistry, and battery storage.

 

  • Fans – Temperature can have a significant impact on the life expectancy of UPS components, internal bearings can wear.

 

  • Electrolytic Capacitors – Typical lifespan of 10 years. Akin to batteries, the biggest risk factor for the projected life of an electrolytic capacitor is temperature and humidity.

 

  • Metal Oxide Varistors (MOVs) – Typically issues will occur after being exposed to frequent and/or extreme voltage spikes.

 

  • Relays – The least likely component to fail in your UPS, however incorrect or malfunctioning firmware setup could result in overuse and lead to failure.
