APC DLA750I DLA750I Power Supply

The APC DLA750I, also sold under the Dell-branded Smart-UPS 750 designation, is a 750VA/500W standalone uninterruptible power supply designed for small server or network closet protection. It provides serial and USB connectivity for host-based monitoring and graceful shutdown, and is fitted with six outlets to protect a small cluster of servers, switches or other critical equipment during a mains interruption. Internally, the unit runs on a pair of voltage-matched 12V 7Ah sealed lead-acid batteries, which are field-replaceable without needing to retire the whole UPS once they reach end of life. As a tower-format Smart-UPS, it is well suited to small offices or comms cabinets rather than full rack environments, offering meaningful runtime for essential equipment rather than just enough time for an orderly shutdown. Being available under both the APC and Dell part numbers reflects how widely this unit was OEM-supplied into small-business server deployments during its production run, and compatible batteries and accessories remain readily available on the secondary market. Tech-Star (UK-based, shipped worldwide) supplies the DLA750I for engineers maintaining small-office or comms-cabinet UPS protection.
