Fan-less class I/II medical & industrial PSUs operate to 80°C
Intended for application areas including home healthcare, medical, dental, test and measurement, broadcast and industrial equipment, the U-channel models measure 64 x 116 x 38.5 mm (WxLxH) and can be conduction cooled using a cold plate to provide 150W at 50°C, 100W at 70°C and 50W at 80°C. With 1m/sec airflow the output power can be increased to 140W at 70°C and 75W at 85°C. The open frame version has the industry standard 50.8 x 101.6 mm (2 x 4 in.) footprint and a height of 31.5 mm. With convection cooling the output power is 120W at 40°C and with forced air cooling it can also deliver 150W at 50°C, 140W at 70°C and 75W at 85°C. An optional cover or a top mounted fan is also available.
Currently, the CUS150M is available with 12V, 24V and 48V outputs, with 15V, 18V, 28V and 36V outputs to be released early 2018. All models can operate from an 85 to 264 Vac input, have efficiencies of up to 94% and an active average efficiency of >91%. No load power consumption is <500 mW. The series has an input to output isolation of 4,000 Vac (2 x MoPP), an input to ground isolation of 1,500 Vac (1 x MoPP) and an output to ground isolation of 1,500 Vac (1 x MoPP) for suitability in B and BF rated medical equipment. The leakage current is <250 µA and touch current is <100 µA. The maximum operating, transportation and storage altitude is 5,000m.
