The Cosel MMC75A-1-J is an open frame AC/DC power supply converter designed for ITE (Commercial) applications. It features a chassis mount type and operates with an input voltage range of 85-132 VAC or 110-170 VDC.
This converter provides three output voltages: +5V at 1.2A, +12V at 0.1A, and -12V at 0.1A. It boasts a typical efficiency of 68% at 100V AC input and has an inrush current of 20A typical. The operating temperature range is from 0°C to 65°C.
Key specifications include line regulation of 20mV max for the +5V output and 48mV max for the +/-12V outputs. Load regulation is 60mV max for +5V and 120mV max for +/-12V outputs. Ripple is rated at 80mVp-p max for +5V and 120mVp-p max for +/-12V outputs.
Safety features include overcurrent protection that automatically recovers. Isolation ratings are AC2,000V 1 minute between input-case/output and DC500V 50MΩ min. Output-case isolation is AC500V 1 minute and DC500V 50MΩ min. Output-output isolation is AC100V 1 minute and DC100V 10MΩ min. The unit complies with UL60950-1, C-UL, and FCC-B conducted noise regulations.
