Power-One XR1648 Power Supply

The Power‑One XR1648 is a high‑efficiency 1.6 kW switching power supply designed for industrial control and server applications, providing 44–56 VDC output from a 100–250 VAC input. Common failure points in this class include degraded capacitors on the DC bus, overheating of the main MOSFETs or IGBT modules, and failure of the internal rectifier (Xscend) due to over‑voltage spikes. First‑check diagnostics: verify input voltage and polarity, measure output ripple and continuity of the DC bus; inspect for visual signs of component burn or bulging caps; and review any error codes from the built‑in monitoring circuitry before proceeding with deeper module replacement.[oss-gpt-20b]
