The CUI Inc. VOF-350-30 is an open-frame AC-DC power supply designed for ITE (Commercial) applications. It provides a single 30VDC output with a maximum continuous power rating of 350W when utilizing 13 CFM forced air cooling. The unit operates within a wide input voltage range of 90-264 Vac and features active power factor correction (PFC).
Key electrical specifications include an efficiency of up to 93%, line regulation of ±0.5%, and load regulation of ±0.5%. It offers protections such as over-voltage, over-current, short-circuit, and over-temperature protection. The operating temperature range is -40°C to 70°C with derating.
Mechanically, the VOF-350-30 has an industry-standard footprint measuring 5.00" x 3.00" x 1.00" (127.0mm x 76.2mm x 25.4mm) and is designed for chassis mounting. It also includes a 12V/0.5A fan output and a standby power consumption of less than 0.5W.
The VOF-350-30 accepts a universal input of 90-264 Vac at 47-63 Hz.
The output is 30 Vdc at up to 11.67 A, providing 200 W with convection cooling or 350 W with 13 CFM forced air.
The operating temperature range is -40°C to 70°C with derating.
It includes over voltage protection (110-140%, hiccup, auto recovery), over current protection (110%, hiccup, auto recovery), short circuit protection (hiccup, auto recovery), and over temperature protection (hiccup mode when PCB exceeds 110±10°C, auto recovery).
The maximum efficiency is 93%.
The dimensions are 127.0 mm (5.00") length, 76.2 mm (3.00") width, and 25.4 mm (1.00") height.
