Vero TRI PK60A FKK 116‑010124A is a 1.5/0.85 A AC‑DC power supply rated at 115/230 VAC, 47–63 Hz, commonly used to provide regulated 5 V and ±12 V outputs for industrial control panels and servo drives. Common failure points on this model include the input bridge rectifier, output voltage regulator ICs (often a linear LM series), and the internal heat‑sink fan or thermal overload protection that can trip under high ambient temperatures. Initial diagnostics should verify the incoming mains voltage and polarity, measure the output rails with an isolated meter while the unit is powered on, inspect for burnt components or loose solder joints, and check the status of any built‑in LED indicators or fault codes if present.[oss-gpt-20b]
