Heat dissipation

37.1 kW / 126.7 kBTU/hr (note 6).

Notes

1.Nominal (Nom): Input current based on rated load, nominal input voltage and fully charged batteries.

2.Current limitation is maximum allowed via electronic current limiting and is based on full battery recharge + nominal load and -10% input voltage.

3.Nominal battery voltage assumed to be 2.0 volts/cell (lead technology).

4.Nominal Battery Discharge current based on rated load, and nominal Battery voltage.

5.Maximum Battery Discharge current based on rated load at end of Discharge.

6.Heat dissipation calculated at rated load capacity.

7.This current is at 125% of rated load and is electronically current-limited to a maximum of 10 minutes. This value is only provided so the engineer can ensure that the selected AC output circuit overcurrent device’s time-current characteristic will support this condition.

8.At 380 V, nominal output is reduced from 200 kW to 180 kW in each section.
