The Cosel MMC75A-2 is an open frame AC/DC converter designed for chassis mounting, suitable for ITE (Commercial) applications. This unit provides three distinct output voltages: +5V at 1.2A, +12V at 0.1A, and -12V at 0.1A.
With an efficiency rating of 75%, the MMC75A-2 operates within an input voltage range of 85-132 VAC and a frequency range of 47-440 Hz. Key electrical specifications include a typical input current of 0.3A at 100V AC, a typical inrush current of 20A, and a hold-up time of 15ms. The power supply offers line and load regulation, with maximum values of 20mV and 60mV for the +5V output, respectively. Ripple noise is specified at a maximum of 80mVp-p for the +5V output.
Environmental specifications include an operating temperature range of 0°C to 65°C and an operating humidity range of 20-90% RH. The unit is designed to withstand vibration and impact, meeting specific standards for these conditions. Safety and noise regulations are met with agency approvals including UL60950-1 and C-UL, and compliance with FCC-B conducted noise standards.
