Six devices plugged into one socket. One power dip and your workstation, modem, and backup drive all go dark. The APC Back-UPS Pro 900VA/540W (MI) gives all six IEC C13 outlets full battery backup and surge protection — no split between 'protected' and 'not protected.' AVR catches the voltage wobble before it hits your gear, so you're not burning through battery life on a 3% dip. The LCD with audible alarms tells you exactly what's happening without you having to lean over. Line-interactive topology, stepped-approximation sine wave, 10 ms transfer time. Lead-acid battery with user-replaceable cartridge (APCRBC164) when the 3-to-5-year window closes. Tower form, not rack-mountable. A-Tick, C-Tick, RCM, and CE certified for Australian use. 45 dBA operating noise — you'll hear it before you see it. In stock now
