The CUI Inc. VOF-275-30 is an AC-DC power supply from the VOF-275 series, designed for industrial and commercial applications. It provides a stable 30V DC output at 9.17A, with a maximum continuous power rating of 160W under natural convection cooling, and up to 275W with forced air cooling.
This converter operates within a wide input voltage range of 80 to 264 Vac and features active power factor correction (PFC) with a typical power factor of 0.95 at full load. It includes essential protections such as over-voltage, over-current, and short-circuit protection with hiccup and auto-recovery modes. The unit also offers a 12V fan output and a standby power consumption of less than 0.5W.
With an industry-standard 3" x 5" footprint and a low profile of 0.75", the VOF-275-30 is suitable for chassis mounting. It operates across a broad temperature range of -40°C to 70°C with derating. Safety approvals include CE, Nemko, UL/cUL, and compliance with standards like EN 60950-1 and IEC.
The input voltage range is 80 to 264 Vac at 47 to 63 Hz.
The output voltage is 30 Vdc and the maximum output current is 9.17 A.
The maximum power is 160 W with natural convection cooling and 275 W with 13 CFM forced air cooling.
The operating temperature range is -40°C to 70°C with derating.
It includes over voltage protection (110-140%), over current protection (110%), and short circuit protection with hiccup mode and auto recovery.
The typical efficiency is 90%.
The package is an open frame module for chassis mounting.
