K-1000 AC Load Bank (Resistive)

The kW of a resistive load bank is “real” power in electrical terms. When a resistive AC load bank is used to test an engine generator set the engine will produce its full horsepower rating, dissipate engine exhaust gases, and produce thermal energy into the engine cooling system. The resistive load bank in fact, will completely test the engine and its various systems.

It is important to understand that the generator or power system will not be loaded to its full kVA rating. Resistive load banks utilize resistors, which only provide kW loading at 1.0 (unity) power factor.
