Inverter Overload Operation

This graph shows how long (measured in milliseconds) the
Freedom HF will operate for a given output current (measured in
Amps).

Both the Freedom HF 1000/1055 models and Freedom HF
1500/1800 models are represented in the illustration below.

The graph illustrates surge operation at 25 °C.
