Alpha’s GMX Series CableUPS® uninterruptible power supply is a cost-effective standby power supply designed for powering signal processing equipment in cable television and broadband LAN distribution systems. It provides a critical load with current-limited, regulated, AC power that is free of spikes, surges, sags and noise. The GMX’s line interactive ferro topology allows it to compensate for input voltage variations of ±30% while providing constant output voltage.

Alpha’s GMX is a cost-effective CableUPS designed for cable operators who need a reliable, basic uninterruptible power supply. Features of the GMX include an embedded status monitoring card slot, smart display, terminal block output connections, 63 and 87V output taps, external battery temperature probe, built-in chassis handle and removable MOV’s.
