Tripp  Lite's compact, all-in-one UPSs (with power module, battery module, and hot-swap PDU module) pack up to 6 kVA into a single chassis as small as four rack units. The Tripp Lite UPSs (either 5 kVA or 6 kVA) feature a 0.9 output power factor (more wattage output capacity) to power more devices than competitive models.
