The Cosel MMC75B-2-N is an enclosed AC-DC power supply designed for chassis mounting. It provides three distinct output voltages: +5V at 1.2A, +15V at 0.1A, and -15V at 0.1A. This unit operates within an input voltage range of 85-132 VAC or 110-170 VDC, with a frequency range of 47-440 Hz or DC.
Key electrical specifications include a typical efficiency of 68% at 100V AC input, line regulation of up to 60mV, and load regulation up to 150mV. The ripple noise is a maximum of 150mVp-p for the +/-15V outputs. Overcurrent protection is built-in, with automatic recovery when the load exceeds 105% of rating.
Environmental conditions for operation include temperatures from 0°C to 65°C and humidity from 20-90% RH (non-condensing) at altitudes up to 3,000 meters. Storage conditions are wider, from -20°C to +75°C. The power supply meets conducted noise standards compliant with FCC-B and carries agency approvals including UL60950-1 and C-UL.
With its robust enclosed design and multiple outputs, the MMC75B-2-N is suitable for various ITE (Commercial) applications requiring reliable power conversion.
