K-1000 AC Load Bank (Resistive & Inductive)

Kongter resistive & inductive AC load banks are used to simulate the motor loads or other electromagnetic devices working at their rated power factor. Many backup generators and turbines are rated at 0.7, 0.8 or 0.85 power factor and need to be commissioned at nameplate capacity using a combination of resistive and reactive load to fully qualify their operating capability. Using a resistive & reactive load bank enables comprehensive testing from a single unit.

Kongter has an extensive range of resistive & reactive load banks to simulate these types of loads on a power source and the transformers, relays, and switches which will distribute the power throughout your facility.


Below is specification for some common models, we build more than these. Please contact Kongter to specify your customized model if you could not find the same model below.
