The Cosel LEA75F-18-R is an open-frame AC/DC converter designed for ITE (Commercial) applications. It delivers a stable 18V output at up to 75W of power.
This converter operates with a universal input voltage range of 85-264 VAC or 120-370 VDC, offering flexibility in power source selection. Key electrical specifications include a typical efficiency of 83% at 100V AC and a power factor of 0.99 at 100V AC. It features overcurrent protection that activates above 105% of rating and overvoltage protection working between 115-140% of rating.
The unit is designed for chassis mounting and has dimensions of 222.0mm x 55.0mm x 29.0mm. It supports features like Power Factor Correction (PFC) and Remote On/Off functionality. The operating temperature range is specified as -20°C to 70°C with derating, though the datasheet also indicates -10°C to +70°C.
Compliance is certified by CE, cURus, and TUV. The RoHS status is listed as RoHS3 Compliant, Moisture Sensitivity Level (MSL) is 1 Unlimited, and REACH status is Unaffected, though these compliance details are currently unverified.
