SurgeX showed its latest UPS surge eliminator, the SU-1000Li, a 1000 VA line interactive UPS that SurgeX says incorporates their Advanced Series Mode patented surge elimination technology to shield computer and AV equipment from catastrophic damage.

The SU-1000Li includes common mode and normal mode Impedance tolerant EMI/RFI filtering, and provides a web browser-based interface to manage power settings, customize diagnostics, monitor multiple computers and schedule shutdowns and restarts. Automatic voltage regulation provides a stable AC source during less than optimal power conditions without the constant use of internal batteries. Housed in a 2U rack-mount enclosure, it stops all surges up to 6,000 volts without producing harmful side effects such as ground contamination or common-mode disturbances.
