1.3.3 Performance Requirements
1.3.3.1 AC Input to UPS
A.
Voltage:
The point at which the UPS transfers to battery operation shall be dependent on the amount of load
that the UPS is supporting. The UPS shall operate from the following voltage ranges without drawing power
from the batteries:

B.
Frequency:
The UPS shall auto-sense input frequency of 50Hz or 60Hz when first powered up and shall use
this frequency as the default output frequency. Once started the input frequency operating window shall be
40-70Hz without going to batteries. The UPS shall be capable of cold start with a default output frequency of
60Hz.
C.
Input Power Factor:
>0.99 lagging at rated load.
D.
Input Current reflected distortion:
5% THD maximum at rated load.
