Fujitsu PSU17A is a regulated DC power supply used in Fuji CR‑IR and Clearview XG‑5000 radiographic systems to provide the 12 V/24 V outputs required by the image detector and control electronics. Common failure modes for this model include internal capacitor degradation, output voltage sag or ripple due to aging electrolytics, and overheating of the heat sink caused by inadequate airflow. First‑check diagnostics: verify input AC voltage and polarity; measure the regulated DC outputs with a multimeter while the unit is powered on; inspect for burn marks, swollen capacitors, or loose connections on the PCB and heat sink. If output voltages are out of spec, replace electrolytic capacitors and clean any dust from the heatsink before re‑testing.[oss-gpt-20b]
