Modified PEM Power Distribution Chassis - LVEA

WP 8523

The PEM power distribution chassis was modified to output ±15V that powers the temperature sensors on BSC1 and BSC3. Trending both temperatures shows temperatures randomly dropping by a few hundred counts. Higher input voltage to the sensors should hopefully clear this issue. Further investigation to be done on BSC1 (ITMY) as temperature values are still lower than expected.
