Spellman SBD40PN280X2890 X2890 Power Supply Repair Service

Professional diagnostic and board-level repair service for this Spellman SBD40PN280X2890 X2890 Power Supply.

The Spellman SBD40PN280X2890 is a high‑voltage power supply used in GE Lunar Prodigy/DPX radiology and bone densitometry systems to provide the 28 kV X‑ray tube drive voltage. Common failure modes for this unit include degraded electrolytic capacitors on the output filtering stages, insulation breakdown or winding damage in the HV transformer, and fuse or rectifier diode burnout that limits current delivery. First‑check diagnostics should verify input AC voltage and line frequency, inspect the main power fuses and rectifier diodes for continuity, and perform a visual inspection of the output capacitors for bulging or leakage before measuring the regulated high‑voltage output with an isolated meter.
