Protect computers, networking equipment, NAS systems and server racks from outages, voltage fluctuations and power disturbances with PowerShield UPS, surge protection and power accessories.
Choose the UPS by the connected equipment’s total wattage, the protection level required and the runtime you need. For most homes and small offices, a line-interactive SafeGuard or Defender is suitable. For sensitive or business-critical equipment, consider Commander pure sinewave or Centurion true online models.
Start with a compact SafeGuard or Defender 650VA-class UPS.
A Defender 1200VA model gives useful capacity for a typical workstation.
Consider Defender 1600VA–2000VA, after checking the actual watt load.
Use a rackmount Defender, Commander RT or Centurion RT matched to the load.
