Safeline LTD. 111960/13 Power Supply is a modular industrial power supply unit typically used in safety‑critical control systems and interconnect boards. Common failure modes for this model include capacitor degradation on the main DC output, overheating of the internal switching regulator, or failure of the protection IC that monitors over‑current and over‑temperature conditions. First‑check steps: verify input voltage and polarity with a multimeter; inspect the unit for burn marks, swollen electrolytics, and ensure all fuses are intact; then test the DC output rails against the specified tolerances and check for any diagnostic LED or fault code indications on the control interface.[oss-gpt-20b]
