The CyberPower LE850G Battery Backup/ uninterruptible power supply (UPS) with line interactive topology safeguards small office workstations, networking devices, and home entertainment systems by providing battery power during power interruptions and surge protection. The LE850G uses Automatic Voltage Regulation (AVR) to correct minor power fluctuations without switching to battery power, which extends battery life. AVR is essential in areas where power fluctuations occur frequently. Data line protection is included for phone/network (RJ11) lines. This UPS offers connectivity via one HID-compliant USB port. The LE850G has a capacity of 850 VA/460 Watts, twelve outlets, four widely spaced to accommodate large transformer plugs. Its maintenance-free battery is user-replaceable.
