AVE450/500 Series1/2砖电源模块

The AVE450/500 series half-brick isolated DC-DC converter provides a single regulated low noise output, 28 Vdc that can deliver up to 16 amps (AVE450B-48S28) or 50V that can deliver up to 10 amps (AVE500-48S50).
型号 : ave450-500-series

The AVE450/500 series have a wide 2:1 input range of 36 to 75 Vdc and is designed primarily for use with standard 48 V telecommunications equipment supplies. The converter’s main application area is in low power and remote radio head (RRH) telecommunications applications.

Rated at 450/500 watts and with an ultra high conversion efficiency of 94% at half load, the converter can operate over an ambient temperature range of -40 to 85˚C, continuing to deliver full power up to a baseplate temperature of 100˚C. The output voltage can be trimmed from 14 to 33 Vdc (AVE450B-48S28) or from 25 to 57 Vdc (AVE500-48S50) to meet a broad range of application needs and there is no minimum load requirement. The conversion technology employs 320 kHz fixed-frequency switching to help minimize external EMI filtering requirements.

Based on a high power density open-frame design that incorporates an aluminum thermal baseplate and is optimized for either conduction or forced air cooling, AVE450/500 series converters have an installed height of just 0.5 inch (12.7 mm), making them ideal for systems with demanding inter-board spacing requirements.

Standard features include input undervoltage lockout, remote On/Off and differential remote sense, as well as comprehensive protection against overtemperature and output overcurrent or overvoltage conditions.
