UPS - SU 1000Li

SU-1000-Li - Surge Eliminator/Power Conditioner

Line Interactive 1000 VA UPS with Automatic Voltage Regulation

Superior to standby UPS products, the SU-1000-Li provides faster response, automatic voltage regulation, and battery backup during a brownout, blackout, surge, or power failure.

Unlike other UPS products, our SU-1000-Li 1000 VA Line Interactive UPS is backed with SurgeX Advanced Series Mode® patented surge elimination technology to shield computer and AV equipment from catastrophic damage. The SU-1000-Li also includes common mode and normal mode Impedance Tolerant® EMI/RFI filtering, and provides a sophisticated web browser-based interface to manage power settings, customize diagnostics, monitor multiple computers, and schedule shutdowns and restarts.

  • Provides A-1-1 Certified fail safe protection from surges, spikes, blackouts, and brownouts.
  • Automatic voltage regulation provides a stable AC source during less than optimal power conditions without constant use of internal batteries.
  • Includes SentryPlus™ UPS power management and diagnostic software.
  • Advanced Series Mode® surge elimination technology stops all surges up to 6,000 volts without producing harmful side effects such as ground contamination or common-mode disturbances, is superior to conventional MOV and MOV-Hybrid circuitry, and is completely non-sacrificial.
  • Over/Under Voltage Protection
  • Credenza Friendly - Only 10.5” deep!
