The Cosel MMC50A-1-J is an open frame AC/DC converter designed for commercial ITE applications. It delivers three regulated outputs: +5V (1.2A), +12V (0.1A), and -12V (0.1A). The converter accepts a wide input range of 85-132VAC (47-440Hz) or 110-170VDC, making it suitable for global use. Typical efficiency is 68% at full load with 100VAC input.
Key electrical characteristics include line regulation of 20mV max on the +5V output and 48mV max on the ±12V outputs, load regulation of 60mV max on +5V and 120mV max on ±12V, and ripple noise of 120mVp-p max on +5V and 150mVp-p max on ±12V. Overcurrent protection activates above 105% of rated current and recovers automatically. The converter also features input-to-case isolation of 2000VAC and output-to-case isolation of 500VAC.
Mechanically, the MMC50A-1-J is an open frame unit with dimensions 173.0mm x 93.0mm x 36.0mm (6.81" x 3.66" x 1.42") and is designed for chassis mount installation. It operates over a temperature range of 0°C to 65°C with derating above certain conditions, and can be stored from -20°C to 75°C. The unit complies with UL60950-1, C-UL, and DEN-AN safety standards, and meets FCC-B conducted noise limits.
