GE IS2020RKPSG2A Product Description
Product Overview
The GE IS2020RKPSG2A is a 6U VME rack power supply module designed for the GE Speedtronic Mark VI turbine control system. It serves as the core power source for VME-based control racks, converting station battery DC input into multiple regulated DC rails for processors, I/O modules and communication circuits.
This unit accepts a 125 V DC main input and delivers a total of 400 W across five independent output voltage levels. It features passive convection cooling with an integrated finned heat sink, and requires no internal fan for operation. The front panel includes status LEDs and a control switch for at-a-glance diagnostics and manual control. Built to industrial turbine control standards, it delivers reliable, continuous power for mission-critical control systems in power generation and heavy process environments.

GE IS2020RKPSG2A
Core Product Features
- Generates five independently regulated DC output rails to support logic, analog, sensor and relay loads across the control rack.
- 400 W total output capacity handles fully populated 6U VME racks with CPU, I/O and communication modules.
- Passive finned heat sink cooling eliminates fan failure points and reduces maintenance requirements.
- Three-color front panel LEDs (green, yellow, red) provide clear visual status for power, fault and warning conditions.
- Built-in overvoltage, overcurrent and short-circuit protection on each rail safeguards downstream modules from electrical damage.
- Standard single-slot 6U VME form factor fits directly into Mark VI control chassis with no custom mounting.
- Top and bottom multi-pin connectors mate directly with the rack backplane for clean, reliable power distribution.
- Wide operating temperature range supports deployment in turbine hall and substation environments without climate control.
