Description

The GE IS2020RKPSG3A serves as a high-capacity power module for the Mark VI Turbine Control System. This series represents a major evolution in the Speedtronic product line for steam and gas turbines. It replaces older control architectures with more sophisticated digital processing capabilities. Consequently, this power supply ensures the continuous operation of critical VME rack components. The module supports heavy-duty industrial automation tasks within global power generation facilities.

Electrical Performance and Output

This power supply module delivers a reliable 400W output to the VME control and interface racks. It specifically requires a nominal 125 VDC input to maintain system stability. Beyond primary power, the hardware provides several specialized secondary outputs. These include one remote +28V PSA output and five standard +28V PSA outputs. Such a configuration allows the module to power multiple auxiliary sensors and control boards simultaneously.

Mechanical Design and Installation

Engineers designed the IS2020RKPSG3A for side-mounting on the right of the VME rack assembly. This orientation optimizes space and heat dissipation within the control cabinet. The unit features a rugged chassis to protect internal electronics from vibration. Furthermore, the front panel includes diagnostic indicators for real-time status monitoring. A Status ID output also allows the central controller to track power health automatically.

Technical Specifications

Compatibility and Environmental Notes

As an “A-rated” revision, this module offers improved reliability over earlier power supply iterations. However, users should note the specific PCB finish during site planning. This version does not feature the heavy conformal coating found on other Mark VI boards. Therefore, the installation environment must remain clean and free from corrosive contaminants. The module communicates status data directly to the DCS to prevent unexpected turbine downtime.
