The CyberPower Intelligent LCD LE1000DG is a compact Battery Backup/ UPS (uninterruptible power supply) with line interactive topology. This model provides battery power and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. The LE1000DG 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. The model's compact design allows for horizontal or vertical placement. It can also be mounted on a wall. Features include PowerPanel® Personal Edition software to control and monitor the UPS, GreenPower UPS™ Bypass Design, and EMI/RFI Filtration.
