The Cosel MMC75B-3-G is an open frame AC DC power supply designed for ITE (Commercial) applications. It features a chassis mount type and provides three output voltages: +5V at 1.2A, +12V at 0.1A, and -5V at 0.1A. The unit operates with an input voltage range of 85-132 VAC or 110-170 VDC and has an efficiency of 75% at full load.
Key electrical specifications include line regulation of 20mV for the +5V output and 48mV for the +/-12V outputs, and load regulation of 60mV for +5V and 120mV for +/-12V outputs. Ripple and noise are rated at 80mVp-p for the +5V output and 120mVp-p for the +/-12V outputs. The power supply has a start-up time of 100ms maximum and a hold-up time of 15ms typical.
Environmental specifications include an operating temperature range of 0°C to 65°C and an operating altitude of up to 3000m. Storage conditions range from -20°C to +75°C. The unit complies with UL60950-1 and C-UL standards and conducted noise complies with FCC-B.
