The IS2020RKPSG3A functions as a VME Rack Power supply within the Mark VI system. The Mark VI is one of the last Speedtronic steam or gas turbine management systems created and released by GE. This line of turbine management ran from the late 1960s when they released the Mark I system through the 1990s with the release of the final two systems, the Mark VI and the Mark VIe. The Mark VI, which can be built in either Simplex or TMR (triple modular redundant) form, is built around a central Control Module. This connects to termination boards that receive inputs from other boards connected to the system. The Control Module is also connected to an Operator Interface, or HMI, that allows access via a Windows platform to system data.
The IS2020RKPSG3A is one of seven (major) versions of the VME Rack Power Supply. Each of these versions has different input and output requirements. The IS2020RKPSG3A has an output rating of 400W. Its input voltage rating is 125 Vdc. The module has a Status ID output, a remote +28V PSA output, and an additional five +28V PSA outputs. The module is designed to mount to the right side of the VME control and interface racks.
The IS2020RKPSG3A module has a front faceplate with a toggle switch that is the only user control on the module. Module faults can be reset using this toggle switch. The faceplate also has three LED indicators, including a green, a red, and a yellow LED. Connections mentioned in the previous paragraph (PSA outputs) are located on the top and bottom of the unit. The side of the unit is designed with a number of metal fins that function as a heat sink component.
The IS2020RKPSG3A is an electronic product developed and manufactured by General Electric for use as a VME rack power supply in Mark VI systems. The Mark VI was the last Speedtronic steam or gas turbine management system created and released by GE.
In Mark VI systems, the IS2020RKPSG3A is one of seven major versions of the VME rack power supply, each with different input and output requirements. The rated output power of this power module is 400W and the rated input voltage is 125Vdc. It has a status ID output, a remote +28V PSA output, and five more +28V PSA outputs. These output designs allow the module to be flexibly adapted to the needs of various industrial and commercial applications.
In addition, the IS2020RKPSG3A module is designed to be mounted on the right side of the VME control and interface rack with a toggle switch on the front panel, which is the only user control on the module. Users can use this toggle switch to reset module faults. There are also three LED indicators on the panel, including green, red and yellow leds, to indicate the module's working status and fault information.
In terms of heat dissipation, the IS2020RKPSG3A is designed with multiple metal fins on the side of the body, which act as cooling components to help ensure stable operation of the power module in high temperature environments.
Overall, the IS2020RKPSG3A is an electronic product with excellent performance and high reliability, which is widely used in industrial automation, energy management, smart buildings and transportation.
