Powec SC‑6A/2A‑6C is a 24 VDC 6 A industrial switch‑mode power supply designed for control and servo applications. Common failure modes on this class of supplies include output voltage sag due to degraded input filtering capacitors, overheating from overloaded or blocked airflow, transformer winding insulation breakdown, and failure of the internal MOSFET driver or gate‑drive ICs. First‑check diagnostics: verify 161–276 VAC input with a multimeter; measure the 24 VDC output under load for voltage droop; inspect the unit for visible signs of overheating (burnt components, swollen electrolytics) and ensure adequate ventilation; review any diagnostic LEDs or error codes displayed on the front panel.[oss-gpt-20b]
