AVO250-48S28 Series


250 W Eighth-Brick Isolated DC-DC Converters

Advanced Energy’s AVO250 series eighth-brick isolated DC-DC converter provides a single regulated low noise 28 VDC output. The converter has a wide 2:1 input range of 36 to 75 VDC and is designed primarily for use with standard 48 V telecommunications equipment supplies. Rated at 250 W, this DC-DC converter can deliver up to 9 A and accommodates an ambient operating temperature range of -40 to 85˚C. Optimized for conduction cooling with an aluminum baseplate option for enhanced thermal performance and thermal transfer, the conversion technology employs 150 kHz fixed frequency switching to help minimize external EMI filtering requirements.
