A Line interactive UPS is one type of uninterruptible power source that can regulate voltage automatically. The line-interactive technology responds to high and low voltage conditions. Units also support systems during outages without battery drainage. With a line-interactive UPS, the electrical source is the first line of power. However, an inverter/converter technology allows for the unit’s battery to be charged throughout normal operations. During an outage, this Uninterruptible Power Supply (UPS)  converts battery power to AC flow for device delivery.
