The VOF-40C-S9 is a 40W AC/DC converter from CUI Inc. designed for a wide range of power supply applications. It accepts a universal input voltage from 85 to 264 VAC at 47 to 63 Hz, with a maximum input current of 1200 mA at 115 VAC and 700 mA at 230 VAC. The converter delivers a stable 9 Vdc output at up to 4.444 A, with an efficiency of 84% typical at 230 VAC input.
The output is well-regulated, featuring line regulation of ±0.5% and load regulation of ±1% from 0 to 100% load. The initial set point accuracy is ±2%. Protection features include over voltage protection set at 20 Vdc for 12 V output models and over current protection at 150-300% of rated output. The hold-up time is a minimum of 50 ms at 230 VAC full load.
Operating temperature range is -25°C to 70°C with derating. The converter has a temperature coefficient of ±0.02%/°C. It is housed in a chassis-mount open frame package with dimensions of 76.2 mm x 50.8 mm x 30.0 mm (3.00 in x 2.00 in x 1.18 in). The switching frequency is 65 kHz.
