The MINUTEMAN PRO-LCD Series of Uninterruptible Power Supplies (UPS) delivers complete protection from electrical problems - spikes, surges, sags, brownouts, and blackouts. Much like the PRO, and PRO-E Series that came before, all PRO-LCD models are amazingly compact and take up little space on the desktop or under a console. The PRO500LCD and PRO700LCD units provide an ample power source for a computer, monitor, and other attached devices with four (6) battery backup outlets with surge protection and two (2) surge-only outlets. The PRO1100LCD and PRO1500LCD models are only slightly larger in physical size, and each offers an expansive six (6) outlets with battery backup and surge along with two (2) surge-only protected receptacles. These units feature heavy power-handling capabilities found in much larger-sized models. This size-to-power ratio makes them ideal for high-power requirement devices installed in cramped quarters.
