VSD Variable Speed Drive

VSD Variable Speed Drive

The Bright III Variable Speed Drive (VSD) Controller? sets a new standard for performance and efficiency.

This advanced system uses self-programming algorithms to automatically adjust between intermittent and continuous pumping modes based on the analysis of the surface dynamometer card. This feature virtually eliminates the need for operator involvement, other than input of basic parameters, while optimizing productivity, power usage, and equipment performance.

This VSD can also serve as a pump-off controller while in the intermittent mode when production or peak run times are met, eliminating the need for physical restarts. In continuous mode, the unit adjusts the speed, running, and idle times to achieve the highest possible pump fillage and production levels.

The Bright III VSD detects failures through sensor output and allows the operator to view alarms either remotely or on site when communications are installed. If the system fails, the controller automatically switches to bypass mode to ensure continued system utilization. The system’s remote monitoring and control feature allows download of all data to a computer through a USB port or when connected to a SCADA system.

For optimal performance levels, the Bright III VSD can be used with a patented auxiliary counterweight. This optional adjustment self-balances in response to changing well conditions.
