The CUI Inc. VOF-180-48 is an AC-DC power supply from the VOF-180 series, designed for reliable power conversion. It provides a 48VDC output with a maximum continuous power of 120W, which can be boosted to 180W with forced air cooling. The unit operates within a wide input voltage range of 80-264 Vac and boasts an efficiency of up to 92%.
Key electrical specifications include line regulation of ±0.5% and load regulation of ±1%. It features protections such as over-voltage, over-current, and short-circuit protection. The power supply also includes a 12V/0.5A fan output and standby power consumption of less than 0.5W.
Designed with an industry-standard 2" x 4" footprint and a low profile of 0.75", the VOF-180-48 is suitable for chassis mounting. Its operating temperature range is -40°C to 70°C with derating. Safety approvals include CB Scheme, EN, FCC, IEC, SIQ, TUV, and UL standards, with isolation voltages of 3000 Vac (input to output) and 1500 Vac (input to ground).
The input accepts 80 to 264 Vac at 47 to 63 Hz, while the output provides a fixed 48 Vdc.
The unit uses an open frame construction designed for direct chassis mounting.
The converter operates reliably from -40°C to 70°C, with power derating applied at higher temperatures.
Full 180W output requires 13 CFM forced air cooling, whereas natural convection limits the maximum output to 120W.
Yes, a built-in trim potentiometer allows for ±3% voltage adjustment located on the SMT side of the PCB.
The unit includes a 12 Vdc fan output capable of supplying up to 0.5A to drive external cooling fans.
