Dell K789 1920W UPS

This UPS has a raft of features, from the advanced battery management, quiet fan, LCD control panel and many output receptacles. These are in two groups, that can be controlled (turned on or off) independantly, very handy. There is also a USB cable to connect to your computer for signalling purposes, and with my windows 7 machiene, it auto detects and works with native drivers (no downloads needed). 

There is a neat illuminated on/off button on the rear of the UPS. 

Also a port for adding external battery banks (72VDC bus). 

Optional network cards (Dell H910 class, ask us if we have any in stock if interested) via the port on the rear of the UPS.
