The GlobTek GTM21097‑5024 is a 24 VDC/2.1 A AC‑to‑DC power supply rated at 50 W with a 100–240 VAC input range and built for industrial or medical equipment such as printers, CCTV cameras, or servo drive accessories. Common failure modes include transformer core saturation or winding insulation breakdown leading to output voltage sag, capacitor degradation causing increased ripple and overheating, and fuse or over‑current protection tripping due to short circuits in the load. First‑check diagnostics: verify input voltage and phase continuity; measure the 24 V output under no‑load and full‑load conditions for regulation within ±5 %; inspect the internal heat sink and fan (if present) for dust or failure, and check the output connectors and solder joints for cracks or cold solder.[oss-gpt-20b]
