The CUI Inc. VOF-15-48 is an AC-DC power supply from the VOF-15 series, designed to deliver up to 15W of continuous power. It offers a single 48V DC output and accepts a universal input voltage range of 85-264 VAC or 120-375 Vdc.
Key electrical specifications include an efficiency of up to 83%, line regulation of ±0.5%, and load regulation of ±1%. The unit provides 3000 Vac isolation between input and output and includes over-current, over-voltage, and short-circuit protections. It operates with a switching frequency of 100 kHz and has a no-load power consumption of less than 0.5W.
Mechanically, this power supply is housed in an open frame, through-hole package with dimensions of 70 x 48.6 x 23.1 mm. It is designed for free air convection cooling and operates within an ambient temperature range of 0°C to 60°C, with derating applied. The VOF-15-48 is suitable for ITE (Commercial) applications and holds UL/cUL and TUV 60950-1 safety approvals.
