The CUI Inc. VOF-275-48-1 is an AC-DC power supply from the VOF-275 series, designed for ITE (Commercial) applications. It provides a 48V output voltage and can deliver up to 160W of power under natural convection cooling, or up to 275W with 13 CFM forced air cooling.
This open frame power supply operates with an input voltage range of 80-264 Vac and features power factor correction (PFC). It boasts an efficiency of up to 92% and a wide operating temperature range of -40°C to 70°C (with derating).
The unit has a compact, industry-standard footprint measuring 5.00" x 3.00" x 0.75". It includes protections such as over-voltage, over-current, and short-circuit protection with hiccup and auto-recovery modes. Safety approvals include CB Scheme, EN, FCC, IEC, SIQ, TUV, and UL.
Key electrical specifications include line regulation of ±0.5%, load regulation of ±1%, and a transient response with a maximum excursion of 4%. It also features a 12V/0.5A fan output and standby power consumption of less than 0.5W.
The output voltage is 48 Vdc.
The maximum output current is 5.73 A.
With natural convection cooling, the output power is 160 W. With 13 CFM forced air cooling, it is 275 W.
The input voltage range is 80-264 Vac.
The operating temperature range is -40°C to 70°C with derating.
Over voltage protection (110-140%), over current protection (110% min), and short circuit protection (hiccup, auto recovery).
The dimensions are 127.0 mm x 76.2 mm x 19.1 mm (5.00" x 3.00" x 0.75").
