General Electric IS2020RKPSG3A Mark VI VME Rack Power Supply
The General Electric IS2020RKPSG3A delivers 400W of power for the Mark VI Speedtronic system. Featuring a 125V DC input and multiple +28V outputs, this module provides the filtered, reliable energy required for critical turbine control and flame detection circuits.
Engineers specifically developed the General Electric IS2020RKPSG3A as a high-capacity VME Rack Power Supply to serve as the heart of the Speedtronic Mark VI turbine management system. This module delivers a robust 400W output, which ensures that critical turbine control hardware receives a stable energy flow. By converting a 125V DC input into various regulated DC voltages, the IS2020RKPSG3A maintains the deterministic performance that utility-scale power generation requires.
Advanced Technical Capabilities
- High-Output Performance:Â The unit provides a 400W power rating, which allows it to support multiple VME rack segments simultaneously.
- Versatile Power Distribution:Â Six independent channels distribute standardized +28V PSA power to individual I/O packs across the system.
- Precision Voltage Regulation: The circuitry supplies the VME backplane with essential voltages, including +5, ±12, ±15, and ±28V DC.
- Fault Management:Â A locking front-panel toggle switch allows operators to control power and manually reset faults.
- Real-Time Monitoring:Â Three distinct LEDs (Green, Red, and Yellow) give technicians instant feedback on operation, malfunctions, and input power health.
- Signal Integration:Â The Status ID output mirrors the green LED, which enables the control system to track the health of the power supply remotely.
Operational Functions and Integration
The IS2020RKPSG3A plays an essential role in high-availability turbine control. In addition to delivering electrical energy, the module improves system intelligence because it communicates its operational status directly to the controller. Because GE designed this unit for the Mark VI VME rack, it mounts securely on a sheet metal bracket on the right-hand side of the assembly. Consequently, the unit occupies a minimal footprint while maintaining easy access for maintenance. Furthermore, the module provides an optional 335V DC output that powers flame detectors directly. As a result, it centralizes diverse power requirements into a single, high-reliability unit. Moreover, users can enable external device support via the P28C output by simply shifting an internal jumper to the “Isolated” position.

GE DS200TCPDG1BEC Mark V Turbine Control Power Distribution Board
Core Functionality in Speedtronic Turbine Systems
The GE DS200TCPDG1BEC operates as a specialized Power Distribution Board (PDB) specifically engineered for the Mark V Speedtronic Turbine Control Series. This board plays a fundamental role in managing and protecting the electrical circuits that drive automated assemblies in steam, gas, and wind turbines. By distributing regulated power across the control architecture, the DS200TCPDG1BEC ensures that critical sensors and actuators receive consistent voltage. Furthermore, because this module belongs to one of the final GE product lines to utilize Speedtronic technology, it remains a vital component for maintaining legacy industrial drive systems.Advanced Circuit Protection and Diagnostic Interface
Regarding its physical layout, the DS200TCPDG1BEC incorporates a robust array of 36 fuses, each housed within a vertical black plastic canister for maximum protection. This design allows technicians to perform rapid maintenance; they simply twist the canister tops to access and replace internal fuses without specialized tools. Moreover, the board features 36 dedicated "OK" LEDs located adjacent to each fuse. These indicators provide immediate visual diagnostics, where a lit green LED confirms circuit integrity and an unlit state signals a blown fuse or a power failure. Consequently, this real-time feedback loop significantly reduces troubleshooting time during system outages.Mechanical Configuration and System Connectivity
To facilitate comprehensive manual control, the DS200TCPDG1BEC includes eight high-quality toggle switches that allow operators to isolate specific power branches. Additionally, the board utilizes a 10-pin connector and four dedicated signal wire terminals to interface with the wider Mark V control network. This specific "BEC" version represents a refined revision of the original "G1" hardware, incorporating enhanced performance specifications over earlier iterations. It is important to note that while the Mark V series is a legacy line, the board’s standardized 29.2 x 27 x 5 cm footprint ensures a precise fit within existing turbine control cabinets.Technical Specifications

Since the module employs a transparent diagnostic system, it empowers maintenance teams to maintain high system availability. Furthermore, the active voice of the status LEDs ensures that power distribution faults never go unnoticed. Although GE has officially discontinued the Mark V series, authentic DS200TCPDG1BEC boards continue to serve as the backbone for reliable turbine operations globally, providing the necessary durability for long-term industrial service.GE IS230JPDMG1B Mark VIe Series Power Distribution (JPDM) Module
​Centralized Power Distribution for Mark VIe Systems
The GE IS230JPDMG1B serves as a specialized Power Distribution (JPDM) Board within the Mark VIe Distributed Control System (DCS). This module functions as a critical junction point, receiving 28 V DC input from external AC/DC or DC/DC converters and distributing it to various system components. Because it supports the heavy-duty requirements of industrial automation, the board provides a steady-state capacity of 24 A across its distribution network. By centralizing the power entry point, the IS230JPDMG1B ensures that controllers and I/O packs receive regulated, reliable voltage, which is fundamental to the stability of the entire control architecture.Flexible Bus Configuration and Redundancy
Regarding its electrical architecture, the IS230JPDMG1B manages three independent power buses designated as R, S, and T. However, the board offers significant configuration flexibility through the use of onboard jumpers, allowing engineers to parallel these buses for redundant power supply applications. This redundancy is vital for high-availability systems where power failure on a single bus cannot be permitted to interrupt the process. Furthermore, the module allows for the interconnection of two adjacent JPDM boards via terminal boards (TB1 and TB2), effectively expanding the distribution capacity for larger, more complex industrial installations.Advanced Diagnostic Feedback and Circuit Protection
In addition to power routing, the IS230JPDMG1B incorporates sophisticated monitoring and protection mechanisms. The board features three fused Mate-N-Lok connectors (JCR, JCS, JCT), each safeguarded by a 10 A fuse to protect downstream loads from overcurrent conditions. To facilitate real-time diagnostics, the module utilizes a DC-62 connector (JA1) to interface with the PPDA I/O pack. This connection transmits feedback signals regarding fuse health and bus voltage status. Moreover, two 50-pin ribbon cable connectors (P1 and P2) allow for seamless diagnostic signal transmission between multiple boards. Consequently, operators can monitor power conditions continuously through the Speetronic MKVI control interface.Technical Specifications
