General Electric IS2020RKPSG1AK VME Rack Power Supply Module

The GE IS2020RKPSG1AK provides essential power distribution for Mark VI control system racks. This high-capacity module converts input energy into multiple regulated DC voltages. It serves as the primary energy source for VME backplanes and critical turbine control components.

Versatile Power Distribution

This module features a complex multi-rail output design to support diverse hardware. It supplies standard logic voltages like +5V and ±12V for processor boards. Additionally, it provides a specialized 335V DC output specifically for flame detector sensors.

Five distinct 28V DC power sections manage energy for external peripheral devices. Users can adjust the power delivery mode via an onboard jumper plug. This allows for seamless switching between standard operation and isolated power configurations.

Intelligent Thermal and Fault Management

Thermal efficiency remains a priority for the IS2020RKPSG1AK hardware. An integrated cooling fan activates automatically based on internal temperature sensors. This demand-based cooling extends the mechanical life of the fan. It also reduces unnecessary power consumption during low-load periods.

Furthermore, the module employs a sophisticated three-tier diagnostic system. Transient faults allow for automatic recovery without technician intervention. Resettable faults require manual clears after resolving the underlying issue. Permanent failures signal the need for immediate hardware replacement to protect the rack.
