6.4. Uninterruptible Power Supply (UPS)
When connected to an AC wall outlet, the DELTA 3 Max Plus can function as an Uninterruptible Power Supply (UPS). In the event of a power outage, it automatically switches to battery power in under 10 milliseconds, providing seamless power to connected devices. This protects sensitive electronics like computers and medical equipment from data loss or interruption.
