The Cosel MMC8A-3 is an open frame AC-DC power supply designed for chassis mounting. It offers a versatile triple output configuration with +5V at 1.2A, +12V at 0.1A, and -12V at 0.1A.
This converter operates with an input voltage range of 85-132 VAC or 110-170 VDC, featuring a typical efficiency of 68% at 100V input. It includes overcurrent protection that automatically recovers when the load exceeds 105% of rating.
Key electrical specifications include line regulation of 20mV for the +5V output and 48mV for the +/-12V outputs, with load regulation ranging from 60mV to 120mV. Ripple noise is specified at a maximum of 80mVp-p for the +5V output and 120mVp-p for the +/-12V outputs.
The unit is designed for industrial applications (ITE Commercial) and meets safety standards including UL60950-1 and C-UL, with conducted noise compliance to FCC-B. Its dimensions are 74.0mm x 68.0mm x 27.0mm.
The input voltage range is 85-132VAC or 110-170VDC.
The operating temperature range is 0°C to 65°C.
