The Cosel MMC75B-3-J is an open-frame AC DC converter with a chassis mount type. It is designed for ITE (Commercial) applications and offers three distinct output voltages: +5V, +12V, and -5V. The converter operates with an efficiency of 75% and has a wide input voltage range.
Key electrical specifications include a +5V output capable of delivering up to 500mA, and +12V and -5V outputs each rated for 0.1A. The unit features overcurrent protection that automatically recovers when the load exceeds 105% of rating. Isolation is provided between input and output with AC2,000V for 1 minute.
Environmental specifications include an operating temperature range of 0°C to 65°C and an operating humidity range of 20-90% RH (non-condensing). The physical dimensions are 193.0mm in length, 93.0mm in width, and 42.0mm in height. Agency approvals include UL60950-1 and C-UL, and it complies with DEN-AN and FCC-B conducted noise standards.
The MMC75B-3-J provides three outputs: +5V at 1.2A, +12V at 0.1A, and -12V at 0.1A.
The AC input voltage range is 85 to 132VAC, and the DC input range is 110 to 170VDC.
The operating temperature range is 0°C to 65°C.
Yes, it has overcurrent protection that activates above 105% of the rated output and recovers automatically.
It complies with UL60950-1 and C-UL standards.
Typical efficiency is 68% at AC 100V input and full load.
It is a chassis mount open frame converter.
