The Vertiv Liebert PSI5 uninterruptible power supply (UPS) is designed to protect and extend the life of your electronic devices in school, home and office. This 4250VA UPS offers cost-effective protection from downtime and damage caused by power outages, brownouts, sags, surges or noise interference. Automatic Voltage Regulation (AVR) extends battery life. Voltage range is from 150 to 281 VAC without using the battery.

This battery backup allows orderly shutdown of critical equipment. It takes less than 6 milliseconds transfer time to battery. With up to 10 minutes of battery backup time at half load and 3 minutes at full load, this reliable system allows ample time for an orderly shutdown during a power outage. A convertible rack/tower design with rotatable LCD display provides flexible installation options.
