BEST FERRUPS 850VA 600W Power Backup

This well constructed, durable BEST Ferrups unit can meet the demands of today's computer loads, including power-factor corrected, switch-mode, and linear power supplies.
The FES850VA has unprecedented ability to work with all types of input sources and loads. Plus, its Active Voltage Regulation converts power from almost any AC source into computer-grade power. The unit provides regulated output voltage without drawing power from the batteries for input voltages as low as 38-percent below nominal (based on size of load). This keeps the batteries fully charged for unexpected blackouts. Additionally, the unit stops harmful harmonic currents generated by widely used switch-mode power supplies (SMPS) from entering a building's wiring, where they could disrupt computer operations. Upon initial power on, the unit initiates automatic startup and performs scheduled diagnostic tests on the logic board, battery, inverter, and other critical systems.

With the CheckUPS II Suite power management software and connecting cable (not included, available through BEST), users can monitor, diagnose, and react more effectively to power-line events, and provides automatic, unattended shutdown when needed. The CD-ROM-based software supports most major operating systems. An optional BestLink SNMP/WEB Adapter can be connected for remote network operations.
I purchased several of these units recently from a local sale. The unit offered appears to be in new condition. All terminals/indicators were in good condition with no sign of scratches/damage observed. The unit should provide years of dependable service! The best price I’ve seen online for this model is $1599 so you can’t beat the deal here ! As with all items I sell, this unit is being sold "as is".
