The Amarad UPS-650D is a line-interactive uninterruptible power supply delivering 650 VA / 450 W of protected output at 230 V. It includes a voltage stabiliser that conditions incoming mains supply before it reaches connected equipment, reducing the impact of voltage fluctuations without switching to battery.

The unit offers RS-232 connectivity for PC-based monitoring, phone line surge protection, and an orange backlit LCD that displays operational status at a glance. A single internal 7.2 Ah / 12 V battery provides backup power, with a transfer time of under 4 seconds on mains failure.
