Functional Features

Status Indication: GE IS2020RKPSG2A uses yellow, red and green LEDs to indicate input power status, fault indication and normal operation.

Power Switch: The front panel of GE IS2020RKPSG2A has a locking power switch that controls the output voltage of the power supply and serves as a fault reset.

Power Supply Function: The main function of the VME backplane power supply is to provide a number of stable DC voltages to the VME backplane, which ensures various components in the VME system operate normally.

Fostering Redundant Operation Support: GE IS2020RKPSG2A adopts in redundant structures, enhancing power supply system reliability, also stability.

Application Fields

Factory Production Lines: In the automated production lines, such as automobile manufacturing and electronic product manufacturing production lines, used as VME-based controllers, sensors, actuators and other equipment power supply. It realizes the automation of production lines, is conducive to the precise control of material transportation, parts assembly, quality inspection and other processes, and improves the production efficiency and product quality.

Distributed Energy Systems: GE IS2020RKPSG2A provides power for the VME system for energy management systems and monitoring systems in solar power plants, wind farms, and other distributed energy systems. That guarantees these systems can manage and control the power generation, energy storage and power consumption of distributed energy, improving the utilization efficiency of distributed energy, and the stability of its access to the power grid.

Power Supply of Aeroengine Test Benches: It provides power to the test equipment and data acquisition equipment of the VME system in the ground test benches of aeroengines. It guarantees that these equipment can accurately acquire the performance parameters of aeroengines, such as thrust, rotational speed, and temperature, and which provide support for the performance evaluation and fault diagnosis of aeroengines.

Smart Grid: For smart grid substations and distribution stations, GE IS2020RKPSG2A is to power the power monitoring equipment and communication equipment of the VME system. It takes such equipment to monitor the power grid parameter in real time real-time, such as voltage, current and power, so to achieve the intelligent dispatching and management of the power grid, and the power grid stability and reliability is improved.

Installation

The power supply is mounted to the right-hand side of the VME rack on a sheet metal bracket. The dc input, 28 V dc output, and 335 V dc output connections are at the bottom. The newer design also has a status connector on the bottom. Two connectors, PSA and PSB, at the top of the assembly mate with a cable harness

carrying power to the VME rack.

Each of the five 28 V dc power modules supplies a section of the VME rack. These sections are labeled A, B, C, D, E, and F. The P28C output or PS28 at the bottom of the power supply can be used to power an external peripheral device. To do this the jumper plug shown on the bracket to the left of the rack must be moved from the Normal position to the Isolated position below.

The fan is only used when the controller is mounted in the rack. It is powered from the top connector on the same bracket, located on the left side of the rack.
