APC Back-UPS 500VA 230V Tower UPS with 4 C13 Outlets

The APC BK500EI is a tower style uninterruptible power supply that delivers 500 volt-ampere or 300 watt of backup power for equipment that relies on a 230 volt mains supply. It is designed to keep a desktop computer, modem router, small server, or point-of-sale terminal running long enough to save work and shut down safely when the electricity goes out.

Four IEC C13 outlets on the rear panel make it easy to protect a full workstation. Three outlets receive both battery backup and surge protection, while a fourth outlet offers surge protection on its own for peripherals that do not need runtime support. An internal surge suppression circuit rated at 310 joules shields connected devices from spikes that often accompany storms or utility fluctuations.

The UPS communicates clearly through an LED status display and audible alarms that announce changes in power conditions, remaining battery capacity, or the need for attention. For deeper insight you can connect it to a PC by either USB or serial cable and use APC software to schedule safe system shutdowns, monitor energy usage, or run self-tests.

Maintenance is straightforward. The battery cartridge can be replaced from the front without taking the unit out of service, and automatic self-testing lets you know well in advance when a replacement is due. A resettable circuit breaker offers quick recovery from overload events, while intelligent charging technology helps extend battery life between changes.

Weighing only 6.3 kilograms and standing upright in a small footprint, the tower fits comfortably under a desk, beside a workstation, or on a shelf in a small office or home office. Whether you are finishing an important document, hosting a conference call, or running critical network gear, this UPS provides the buffer you need to ride out everyday power disturbances with confidence. APC covers the unit with a two-year warranty for additional peace of mind.
