The OPTI ES series provides Automatic Voltage Regulation (AVR) to keep the voltage to your equipment within limits without unnecessarily dropping to battery. An improvement over the offline Uninterruptible Power Supply, the OPTI-UPS ES Series UPS provides protection against surges, spikes, brown outs as well as providing adequate time to close your PC in the event of a power failure.

Available in desk mounting or in rack mounting format from 800VA to 1500VA.

Supplied complete with OPTI's Smart Power Management Software
