Spellman DXR3000X1850 is a high‑voltage DC power supply used in X‑ray generators and medical imaging systems, providing up to 60 kV at 50 mA. Common failures on this model include burnt or tripped protection relays, degraded output capacitors, and insulation breakdown between the high‑voltage section and chassis; overheating of the filament heater can also trigger overcurrent shutdowns. For initial troubleshooting, verify that the mains input voltage is within spec and that the unit’s internal fuses have not blown; check the status LEDs or digital display for fault codes, then perform a visual inspection of the HV output board for cracked solder joints or damaged components before proceeding to measure output voltage with a high‑voltage probe.[oss-gpt-20b]
