Overview

The K Series is an entry-level off-line (backup) UPS that keeps PCs, workstations, POS terminals and small office equipment running through brownouts and blackouts. A wide 145–280VAC input window with automatic voltage regulation (AVR) corrects most mains disturbances without touching the battery, while a typical 2–6ms transfer rides through the switchover.

Cold-start capability, charging while the unit is off and generator compatibility make it a dependable safeguard for locations with unstable utility power. The K3000 adds a pure sine wave output for more sensitive loads.

Key Features

  • Automatic voltage regulation (AVR) stabilizes output as mains rises or drops
  • Super wide 145–280VAC input range
  • Cold start function
  • Automatic charge in off-mode
  • Compatible with generators
  • Microprocessor control for reliable operation; mains restart function
  • Overload, deep-discharge and over-charge protection
