The Cosel MMC75B-3-CN is an enclosed AC/DC converter designed for ITE (Commercial) applications. It features a chassis mount type and provides three output voltages: +5V at 500mA, +12V at 1.1A, and -5V at 0.1A. The converter operates with an input voltage range of 85-132 VAC or 110-170 VDC and has an efficiency of 68% at 100V AC input with full load. It includes overcurrent protection that automatically recovers. The unit is approved by UL60950-1 and C-UL, and complies with DEN-AN and FCC-B conducted noise standards. Its dimensions are 193.0mm x 93.0mm x 42.0mm, with a maximum weight of 150g.
Key specifications include a typical hold-up time of 15ms and a start-up time of 100ms max. Isolation ratings are AC 2,000V between input and output, AC 500V between output and case, and AC 100V between outputs. The operating temperature range is 0°C to 65°C, with humidity from 20% to 90% RH non-condensing, at altitudes up to 3,000m. Storage conditions are -20°C to +75°C and 20% to 90% RH non-condensing, at altitudes up to 9,000m. The device also meets vibration and impact standards.
The MMC75B-3-CN provides three outputs: +5V at 500mA, +12V at 1.1A, and -5V at 0.1A.
The input voltage range is 85-132VAC (single phase) or 110-170VDC, with a frequency range of 47-440Hz.
The operating temperature range is 0°C to 65°C, with derating required at higher temperatures.
The converter has overcurrent protection that activates above 105% of rated output and recovers automatically.
Isolation is AC 2,000V between input and case, AC 500V between output and case, and AC 100V between outputs.
The typical efficiency is 68% at full load with 100VAC input.
The converter measures 193.0mm x 93.0mm x 42.0mm, weighs 150g max, and is designed for chassis mounting.
