Tripp Lite BC500 500VA UPS 8 Outlets

Compact 500VA UPS for desktop and wall mounting

The Tripp Lite BC500 is a 500VA battery backup unit that supplies 110V, 115V or 120V AC output through eight NEMA 5-15R outlets. It uses a valve-regulated lead-acid battery to protect connected equipment from blackouts, brownouts, overvoltages, surges and line noise. The unit weighs 4.7 units and is designed for desktop or wall installation. It suits home offices, media centres, kiosks, security systems and digital signage.

Four outlets provide battery backup, four surge-only

Only four of the eight NEMA 5-15R outlets deliver battery-backed power during an outage; the remaining four supply surge protection without battery support. The unit is rated at 260W maximum output, so the combined load on the battery-backed outlets must stay within this limit. Backup duration varies with load, but an energy-efficient desktop with a small LCD monitor can run for up to 18 minutes. Exceeding the wattage rating will reduce runtime or trip the overload protection.

Verify outlet count, voltage

Confirm that your devices use NEMA 5-15R plugs and that the total power draw of equipment needing battery backup does not exceed 260W. Ensure the installation site can accommodate a 4.7-unit weight device mounted on a desk or wall. The replaceable internal battery charges from utility power during normal operation, so a functioning mains supply is required to maintain readiness. Buyers needing more than four battery-backed outlets or a higher wattage rating should consider a different unit.
