QHL75 Series DC-DC CONVERTER BASEPLATE 75W COOLED The QHL75 series oerff s a compact 75W DC-DC solution in an industry standard quarter brick package. This series of modules enables eectivff e construction of distributed power architectures from AC front ends, PFC front ends and baerytt systems. Utilizing the integral baseplate for conduction cooling gives the designer flexibility in system design. Constructed with reinforced insulation, the QHL series features an industrial operating temperature range and includes protection for over current, over temperature and over voltage. Features 180 - 450VDC Input Range Applications Baseplate cooled Industry standard brick package Regulated single outputs from 5 to 48VDC Industrial LED Lighting Robotics Technology Output voltage trim 20% (5V: -20%/+10%) Electronics 3.0kVAC reinforced isolation Dimensions Efficiency up to 90% 2.28 x 1.45 x 0.50 (57.9 x 36.8 x 12.7 mm) Short circuit, overvoltage & overtemperature protection Remote On/Off -40C to +105C operating temperature 3 year warranty Models & Ratings (1) Input Current Efficiency at Vin Ripple & Noise Maximum Model Number Input Voltage Output Voltage Output Current Nominal with Full Load at Vin (2) pk-pk Capacitive Load No Load Full Load Nominal QHL75300S05 5V 15.0A 0.30A 100mV 82% 15000F QHL75300S12 12V 6.25A 0.28A 150mV 88% 6250F 300VDC QHL75300S15 15V 5.0A 10mA 0.28A 150mV 90% 5000F (180-450VDC) QHL75300S24 24V 3.12A 0.28A 240mV 90% 3300F QHL75300S48 48V 1.56A 0.28A 480mV 89% 1000F Notes: 1.
