PC based load bank controller

The Sigma PC Load Control is a Windows-based alternative to the Intelligent Hand Held Terminal (IHT) on a Froment Sigma-equipped load bank. It provides enhanced load control, transient-speed instrumentation, real-time graphs, full data acquisition and reporting.

Load control and data capture can be controlled manually or automatically. Instrumentation measurements are made using high accuracy voltage and current transformers located within the load bank and the data is saved to disk along with the active supply details. Data can be printed out in report format, as in this example, or exported for analysis using other software packages.

The Sigma PC System is developed in-house using Microsoft® Visual Studio.
