As a follow up to our Lighting inverter series, this article will focus on the components of a lighting inverter and how they may differ from a UPS. UPS systems are typically used for critical power applications where both power conditioning and uninterrupted power is required. They typically have shorter run time and rely on batteries to keep the system running in the event of an outage. While there are UPS systems that are UL924 approved, a UPS is typically used in non-lighting applications such as data centers, hospitals and other critical environments, keeping your servers, computers and other equipment operational in the event of a power outage. A lighting inverter is similar to a line-interactive UPS, where the unit passes utility power to support systems until there is an outage, then draws from batteries to provide power during the outage window.
