DC-DC Converters
QSB15048W Series
150W wide input 8:1 half brick baseplate cooled DC-DC converters for ITE & industrial electronics applications
The QSB15048W series have an ultra-wide 8:1 input voltage range of 9 to 75VDC providing a flexible single solution for nominal inputs of 12, 24 & 48VDC, making these devices particularly suitable for mobile applications running from battery or vehicle supplies.
Baseplate or heatsink cooling allows operation over a wide temperature range from -40°C to +100°C. Standard features include both remote On/Off and remote sense. Protection features include input under-voltage lockout, overvoltage, short circuit and over load conditions while providing thermal shutdown in overtemperature conditions. Isolation voltage is 1.5kVDC and the output is tightly regulated to within ±0.2% for line changes and ±0.2% maximum under all load conditions.
