Powerexpert has recently completed an important milestone on a multi-year development project. A 438kW, 834ADC, 525V AC-to-DC plasma torch converter retrofit system was successfully designed, developed, manufactured, and commissioned inside a customer’s existing power supply. The system was successfully installed (a true drop-in replacement) and started up. The system is currently running and the customer…
Control Board Clone Successfully Commissioned
Powerexpert has successfully cloned a control board that the original manufacturer no longer supports, had little documentation, and suffered from many obsolete components. The scope of work included assessment of the components, re-engineering obsolete components/circuits, developing a modern bill of material, manufacturing, delivery, and integration into the customer’s system. Two board assemblies were successfully commissioned…
