FUNCTIONAL DESCRIPTION:
IS2020RKPSG2A is a VME Rack Power Supply Module manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic gas turbine control systems. The Mark VI VME rack power supply mounts on the side of the VME control and interface racks. It supplies + 5, ± 12, ± 15, and ± 28 V dc to the VME backplane, and an optional 335 V dc output for powering flame detectors connected to TRPG. Two supply input voltage selections are available. There is a 125 V DC input supply that is powered by a Power Distribution Module (PDM) and a low voltage version for 24 V DC operation. Except for the number of remote 28 V outputs, the RKPSG2 and LVPSG2 are designed to be direct replacements for the RKPSG1 and LVPSG1 respectively.
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.
OPERATION:
The VME Rack power supply has only one user control, the power switch, and three status LED indicators. The power switch provides front-panel control of the power supply output voltages and when toggled serves as a fault reset. The yellow, red, and green LEDs indicate the status of the input power, fault presence, and normal operation.
The front panel power switch is a locking type that must be pulled out to change position. This switch is a low voltage control to enable or disable the output voltages. If the red LED is ON indicating a fault condition the power switch can be toggled OFF and then back ON again to clear the fault. The fault will only be cleared if the condition that caused it no longer exists.
CONFIGURATION:
An external peripheral device can be powered via the P28C output or PS28 at the base of the power supply. The jumper plug on the bracket to the left of the rack needs to be switched from the Normal position to the Isolated position below to accomplish this.
The 5 V current limit is a special case due to the 5 V under-voltage detector. If the current limit causes the 5 V output voltage to fold back below the UV threshold, all of the other outputs will be disabled until the 5 V output voltage returns to a voltage above the UV threshold.
