ADH1300 Series
1300 W Half-Brick DC-DC Converter
The ADH1300 series half-brick isolated DC-DC converter provides a single regulated 28 V/46.5 A low-noise 1300 W output with > 95% efficiency at half load. With an input range of 36 to 75 VDC, the series is designed primarily for standard 48 V telecom equipment, such as remote radio head (RRH) applications. A fixed 300 kHz switching frequency minimizes external EMI filtering requirements. An open-frame design with an aluminum thermal baseplate is optimized for conduction or forced air cooling. You can operate the ADH1300 converters over -40 to +85˚C ambient and with full power delivery up to a baseplate temperature of 100˚C. The unit follows the standard 1/2 brick dimensions of 2.3″ (57.9 mm) * 2.4″ (61 mm) and an installed height of just 0.5″ (12.7 mm).
