XP Power QHL75 75W Baseplate-Cooled DC-DC Converters

XP Power QHL75 75W Baseplate-Cooled DC-DC Converters offer a compact DC-DC solution in an industry-standard quarter-brick package. These devices enable the effective construction of distributed power architectures ranging from AC front ends, PFC front ends, and battery systems. The QHL75 converters utilize an integral baseplate for conduction cooling which gives users system design flexibility. Constructed with reinforced insulation, the QHL75 75W Baseplate-Cooled DC-DC Converters operate in an industrial temperature range of -40°C to +105°C and feature over-current, over-temperature, and overvoltage protection.
