The Versatile Measuring Inst. 1192 is an industrial switching power supply designed to deliver regulated DC output (typically 12–24 V) to instrumentation or control circuits. Common failure modes for this class include degraded MOSFETs, burnt capacitors on the input/output filter stages, and failed protection ICs that trigger over‑current or short‑circuit shutdowns. Begin troubleshooting by verifying input voltage and polarity with a multimeter, then check output rails under load; inspect the board for bulging or cracked electrolytics and look for visible scorch marks around the switching regulator. Finally, review any fault codes or LED status indicators that may point to specific protection trips before proceeding to component replacement.[oss-gpt-20b]
