GE IS2020RKPSG3A VME Rack Power Supply Module 400W Mark VI

The GE IS2020RKPSG3A is a VME Rack Power Supply Module, a key component of GE’s Mark VI Turbine Control System Series—one of the last Speedtronic-based systems and an upgrade over the Mark V. As a 400W standalone power supply, it mounts on the right-hand side of VME control/interface racks via a sheet metal bracket, delivering 125V DC input and outputs including a Status ID signal, 1 remote +28V PSA output, and 5 additional +28V PSA outputs. It also supports optional 335V DC output for external devices and can power peripherals via P28C/PS28.

Designed with a front faceplate featuring a locking toggle switch and three status LEDs, it simplifies monitoring. Its side-mounted metal fins act as a heat sink, and top/bottom connectors facilitate wiring. It is a derivative of the IS2020RKPSG3 parent module and works with the IS2020LVPSG1, integrating into both simplex and TMR Mark VI setups via the central Control Module.

Key Features
Power Specifications: 400W output rating, 125V DC input, and multiple outputs to power VME backplanes, rack sections, and external peripherals.

Drop-In Compatibility: Part of 7 major VME power supply versions, designed for Mark VI systems and works with IS2020LVPSG1. Serves as a reliable replacement in existing Speedtronic turbine setups.

User-Friendly Design: Front-panel locking toggle switch resets faults and controls outputs; three LEDs for clear status tracking. Side metal fins act as a heat sink for thermal management, ensuring stability in harsh industrial environments.

Installation Flexibility: Mounts on VME rack right-side via sheet metal bracket. Top and bottom connectors simplify wiring; jumper switch enables “Isolated” mode for peripheral power. Detailed steps guide safe removal/installation.
