"The following table gives typical thermal dissipation as a function of mode of

operation. The models listed below are 120V and 230V versions of PowerStack

250 and 450. On-battery thermal dissipation is given at full rated load over

the entire battery discharge period. Note that on-battery thermal dissipation

is limited in duration according to available battery capacity and output

loading.

Model	Operating On-line Watts [BTU/Hr]	Operating On-battery Watts [BTU/Hr]
250	16[55]	35[120]
450	10[34]	75[256]
