Description
Product Introduction
⚡ Product: IS2020RKPSG3A
🏷️ Brand: GE / General Electric
🔧 Series: Mark VI Speedtronic
🔋 Product Type: VME Rack Power Supply Module
The GE IS2020RKPSG3A is a VME rack power supply module used in GE Mark VI turbine control systems. It is designed to provide regulated DC power to the VME control and interface rack and associated Mark VI control hardware. The IS2020RKPSG3A is identified as a 400 W version with a nominal 125 VDC input.
🔌 The module provides a status ID output, one remote +28 V PSA output, and five additional +28 V PSA outputs. It is mounted on the right side of the Mark VI VME control/interface rack. The front panel includes a toggle switch for power control and fault reset, together with green, red, and yellow status LEDs.
🏭 The module is primarily used in GE Mark VI gas and steam turbine control systems and is suitable for maintenance, system replacement, and legacy turbine-control spare-parts applications.

Installation & Use
🛠️ Before installation, verify the complete IS2020RKPSG3A part number, input voltage, hardware revision, rack configuration, and existing power-distribution arrangement.
🔌 Disconnect the rack from its power source before removing or installing the module. Confirm the 125 VDC input and inspect the power connectors and backplane connections before energizing.
💡 After startup, check the green, red, and yellow status indicators. Verify the +28 V PSA outputs and the rack’s downstream DC supply voltages before starting the turbine-control application.
📊 Check the Mark VI controller, VME modules, VCMI/VDSK equipment, and associated diagnostics for normal operation after power-up.
⚠️ The IS2020RKPSG3A is a rack-level power supply. Confirm the exact input/output configuration before substitution, since different GE Mark VI VME power-supply variants have different electrical requirements.
