The Cosel MMC75B-1-GN is a versatile AC-DC converter designed for various applications. This enclosed unit features a chassis mount for easy integration into systems.
It provides three output voltages: a primary +5V output capable of 1.2A, a +12V output at 0.1A, and a -12V output also at 0.1A. The converter operates with an input voltage range of 85-132 VAC and has a typical efficiency of 75% at full load. Key electrical specifications include line regulation of 20mV for the +5V output and 48mV for the +/-12V outputs, with load regulation figures of 60mV and 120mV respectively. Ripple and noise are kept within limits, with maximums of 80mVp-p for the +5V output and 120mVp-p for the +/-12V outputs.
Environmental specifications include an operating temperature range of 0°C to 65°C and operating humidity from 20% to 90% RH. The unit is designed to withstand vibration and impact as specified in the datasheet. Safety and noise regulations are met with UL60950-1 and C-UL approvals, and compliance with FCC-B conducted noise standards.
Isolation ratings are robust, with 2000V AC between input and output, 500V AC between output and case, and 100V AC between outputs. The dimensions are 193.0mm x 93.0mm x 42.0mm.
The input voltage range is 85-132VAC (single phase) or 110-170VDC.
The converter provides +5V at 1.2A, +12V at 0.1A, and -12V at 0.1A.
