Description
Overview
The IS2020RKPSG1AK VME Rack Power Supply Module is a GE‑designed power conversion unit used in Mark VI control architectures. It provides regulated DC outputs for VME‑based control racks and peripheral devices, ensuring stable and uninterrupted operation in turbine and process‑control environments. Its multi‑voltage capability and diagnostic intelligence make it a central component in high‑availability control systems.
Functional Characteristics
This module distributes several isolated DC outputs required by VME rack electronics, including +5 V, ±12 V, ±15 V, and ±28 V. An additional high‑voltage output (335 VDC) is available for flame‑detection hardware. The IS2020RKPSG1AK supports dual input supply options—24 VDC or 125 VDC—allowing flexible integration into different power architectures.
Internally, the unit incorporates multiple 28 VDC conversion stages and a configurable output section for external loads. Cooling is managed automatically through a rack‑mounted fan that activates based on thermal demand, improving efficiency and extending component life.
Protection and Diagnostics
The power supply includes a multi‑level protection system designed to isolate faults and maintain system continuity:
-
Automatic recovery for transient disturbances
-
Manual reset for recoverable faults
-
Lockout for non‑recoverable failures requiring module replacement
A jumper‑selectable mode allows the user to switch between standard rack operation and isolated output mode for powering external devices. Status monitoring is available through dedicated connectors on the front panel.
Mechanical and Installation Details
The module is built with a reinforced enclosure suitable for industrial environments. Its form factor fits standard VME rack assemblies used in Mark VI systems.

FAQ
Q: Does the module support redundant power configurations? A: Yes. It can be used in redundant rack power architectures depending on system design.
Q: Can the 335 VDC output be disabled? A: The high‑voltage output is optional and depends on system configuration and flame‑detector requirements.
Q: Is the module hot‑swappable? A: Hot‑swap capability depends on the specific rack configuration; many Mark VI racks require controlled shutdown before replacement.
