The Cosel MMC75A-4-J is a triple-output AC/DC converter designed for commercial ITE applications. It accepts a wide input range of 85-132 VAC (47-440 Hz) or 110-170 VDC, and provides three regulated outputs: +5V at 1.2A, +12V at 0.1A, and -12V at 0.1A. The converter achieves a typical efficiency of 68% at full load (100VAC input).
Key electrical specifications include line regulation of 20mV (V1), 48mV (V2, V3); load regulation of 60mV (V1), 120mV (V2, V3); and ripple noise of 120mVp-p (V1), 150mVp-p (V2, V3). The unit features overcurrent protection that activates above 105% of rated output and recovers automatically. Isolation ratings are 2000VAC input-to-case/output, 500VAC output-to-case, and 100VAC between outputs.
The MMC75A-4-J is housed in an open-frame package measuring 193.0mm x 93.0mm x 42.0mm and is designed for chassis mounting. It operates over a temperature range of 0°C to 65°C with derating, and complies with UL60950-1, C-UL, and DEN-AN safety standards, as well as FCC-B conducted noise limits.
