The Lambda Vega 650 K60113 is a 650‑W modular AC‑DC power supply rated 120–240 V with selectable outputs up to 64 V/120 A; it is commonly used in industrial control cabinets and servo drive systems. Common failure modes for this model include capacitor degradation on the main rectifier board, fan motor burnout or bearing wear leading to overheating, and output transformer winding insulation breakdown under fault conditions. First‑check diagnostics should verify input voltage and phase balance with a multimeter, inspect the internal heat sink and fan for dust accumulation or mechanical damage, and test each output rail for correct voltage and ripple using an oscilloscope before proceeding to component replacement.[oss-gpt-20b]
