The VOF-40C-S3 from CUI Inc. is a 26W AC/DC converter designed for applications requiring a regulated 3.3V output. It accepts a universal input voltage from 85 to 264 VAC at 47-63 Hz, making it suitable for global use. The converter delivers a maximum output current of 8A with a typical efficiency of 76% at 230 VAC input, minimizing power loss.
Protection features include overvoltage protection (7.5 VDC), overcurrent protection (hiccup mode, 150-300% of rated current), and short circuit protection with auto-recovery. Ripple and noise is limited to 100 mVp-p, and the initial set point accuracy is ±3%. Line regulation is ±0.5% and load regulation is ±1%.
The converter is packaged in an open frame chassis mount configuration with dimensions of 76.2 mm x 50.8 mm x 30.0 mm. It operates over a temperature range of -25°C to 70°C with derating required above 50°C. The switching frequency is 65 kHz, and hold-up time is 50 ms at 230 VAC full load.
