It delivers 950 VA of power and features six C13 outlets with surge protection to keep devices such as computers, NAS systems, and network hardware like routers and modems operational.

This model offers comprehensive surge protection against voltage spikes from lightning strikes and includes 1-Gigabit network data line surge protection for Ethernet connections without sacrificing speed. Its fanless design operates quietly, making it suitable for office or home environments. The internal battery cartridge (RBC17) is user-replaceable, extending the product's lifespan. Automatic Voltage Regulation (AVR) corrects low and high voltages without discharging the battery, optimizing runtime and battery life. PowerChute Personal Edition software and a USB cable are included for advanced management. The case is black and measures approximately 28 cm in width, 15 cm in height, and 40 cm in depth, with a weight of around 12 kg. This UPS is ideal for maintaining uptime and protecting sensitive electronics from power interruptions.
