Artesyn AVE350 series isolated 28V DC-DC converters

The AVE350B series of isolated DC-DC converters is designed specifically to provide the main 28VDC supply for RF power amplifiers in small-cell, low power and Remote Radio Head (RRH) telecommunications applications. The series comprises two single output models: the AVE350B-24S28-6, which accepts a wide range input from 18VDC to 36VDC; and the AVE350B-48S28-6, which accepts a wide range input from 36VDC to 75VDC.

AVE350B series converters are capable of delivering up to 12.5A. Rated at 350W, they can operate over an ambient temperature range from -40˚C to +85˚C, continuing to deliver full power up to a baseplate temperature of +100˚C. Both models offer a wide output voltage trim range to meet a broad range of application needs and have no minimum load requirement. The AVE350B-24S28-6 can be trimmed from 14VDC to 33VDC, while the AVE350B-48S28-6 can be trimmed from 16.8VDC to 33VDC. Both converters use fixed-frequency switching to help minimize external EMI filtering requirements.
