1.

Rectifier operates at any of the rated supply voltages and frequencies without further adjustment.

2.

At 305V input mains, the UPS maintains the specified output voltage at rated load without discharging a previously charged battery.

3.

EN 50091-3: at rated load and input voltage 400V, battery charged

4.

EN 50091-3: at rated load and input voltage 400V, battery charging at maximum rated power.
