AGQ300-48S1V2 Series


72 W Quarter-Brick Isolated DC-DC Converters

The AGQ300-48S1V2 series quarter-brick isolated DC-DC converter produces a single fully regulated output voltage of 1.2 VDC. Rated at 72 W, the converter can deliver up to 60 A output current. It 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.

AGQ300-48S1V2 series converters have a typical efficiency of 85% and accommodate an ambient operating temperature range of -40 to 85˚C. Their open-frame design is optimized for forced air or conduction cooling and an aluminum baseplate option is available for enhanced thermal performance. The conversion technology employs 300 kHz fixed frequency switching to help minimize external EMI filtering requirements.

Standard features include output trim, remote enable and differential remote sense, with overtemperature and non-latching overvoltage and overcurrent protection. AGQ300-48S1V2 series converters are low profile modules that are ideal for systems with demanding inter-board spacing requirements – the baseplate version has an installed height of 0.5 inch (12.7 mm) and the open-frame version requires 0.4 inch (10.1 mm).
