Description
The Ewent EW3997 is a black line-interactive uninterruptible power supply with an output power capacity of 1.3 kVA and 720 W. It features automatic voltage regulation (AVR), so it operates with an input and output voltage of between 100 V and 230 V, at a frequency of 50/60 Hz. Its waveform is pure sine wave and its response time is 8 ms, so it protects connected equipment against overloads, excessive discharges, short circuits and overvoltages. It has 3 AC outlets with Type F connector, with the same outlet type. It has audible alarms for fault, low battery and overload. Its dimensions are 170 x 140 x 345 mm (width x height x depth) and its weight is 10 kg, dimensions that should be taken into account when positioning it.
