The Condor D12-16‑D is a 120VAC, 60 Hz AC‑to‑DC adapter rated at 12 VDC, 1.5 A (≈35 W). Common failure modes for this class of low‑power industrial supplies include capacitor degradation in the rectifier/filter stage, overheating of the internal switching regulator or transformer winding, and burnout of the output diode or protection fuse. First‑check diagnostics: verify input voltage with a multimeter, confirm that the output is 12 VDC at no load, visually inspect for bulging capacitors or scorch marks, and test the output current capability by measuring under a known load. If the supply fails these checks, proceed to replace the filter capacitor bank or the switching regulator IC as appropriate.[oss-gpt-20b]
