The first, the AVE family, is a half-brick format offering higher than 94% typical efficiency and excellent thermal performance, making it suitable for small space and high power applications. An aluminium baseplate structure makes it possible for the modules to operate between -40 and +85C ambient temperature, and the AVE family can continue to operate at full power up to 100C baseplate temperature – all without forced-air cooling.
The first models in the AVE family offer a single 28 Vdc output and either 450W at up to 16A current output (AVE450B-48S28), or 350W at 12.5A current output (AVE350B-48S28-6). AVE converters offer a wide trim range of typically 60 to 118% of Vout and up to -50% to +118% of Vout. Other features include remote control, remote output sense, trim; and protection features such as input under voltage lockout, output over current protection, output over voltage protection, and over temperature protection.
AVE units include a dual-output model (AVE450-48D2805), which enables network equipment providers to use fewer components in their designs and so save space and cost. It delivers up to 12A output current with 28V output voltage and 20A with 5.5V output voltage, which is widely adjustable from 4.5V to 12V, for powering digital circuitry. The dual-output AVE model offers higher than 92% efficiency and the same thermal performance as the rest of the AVE series.
The second new family of DC-DC converters, the AGF family, comes in a standard full-brick format with aluminium baseplate structure and power levels of 600, 700 or 800 W with up to 28.6A output current. It offers higher than 94% typical efficiency and excellent thermal performance. At 800W power output, the AGF800 series is the highest power dc-dc module ever produced by Artesyn.
