The XP Power VFT80US24 is an AC/DC converter that provides a regulated 24V output with up to 80W of power. It accepts a universal input voltage range of 85-264 VAC at 47-63 Hz, with an internal T3.15A/250V fuse for input protection. Typical efficiency is 88%, and no-load input power is less than 0.5W.
The converter features line regulation of ±0.5% max, load regulation of ±1.0% max, and ripple and noise of 1% max pk-pk. Transient response is 4% maximum deviation, recovering to less than 1% within 500µs for a 50% step load. Switching frequency is 60 kHz ±10 kHz. Hold-up time is 8 ms typical at full load and 115 VAC.
Protection features include overvoltage protection (refer to specifications for specific thresholds), overload protection with a range of 110-180% of rated output, and hiccup-mode short circuit protection. The unit operates over a temperature range of -10°C to 70°C with derating from 100% load at 50°C to 50% load at 70°C. Storage temperature range is -40°C to +85°C.
The VFT80US24 meets EN55032 Level B for conducted and radiated emissions and EN61000-3-2 Class A for harmonic currents. Isolation is rated at 3000 VAC input-to-output, 1500 VAC input-to-ground, and 500 VDC output-to-ground. MTBF exceeds 320 kHrs per Bell Core issue 6. The 24V version does not include remote sense or output trim.
