The Cosel LEA75F-12-SN is an enclosed AC/DC converter designed for ITE (Commercial) applications. It provides a 12V output with a maximum current of 6.3A, delivering up to 75W of power. This converter features universal input voltage ranging from 85-264 VAC or 120-370 VDC, along with power factor correction (PFC) for improved efficiency.
Key electrical specifications include an efficiency of up to 80% at 200V input, line regulation of 48mV maximum, and load regulation of 100mV maximum. The ripple and noise are kept to 150mVp-p at 0 to +50C. It offers robust protection features such as overcurrent protection working above 105% of rating and overvoltage protection between 115-140% of rating.
Designed for chassis mounting, the LEA75F-12-SN has dimensions of 222.0mm x 55.0mm x 29.0mm. It operates within an ambient temperature range of -20°C to 70°C with derating. The unit also boasts high isolation ratings, including 3000 VAC between input and output.
