The Cosel PMC75E-4 is a robust enclosed AC/DC converter engineered for industrial and commercial information technology equipment.
Designed for chassis mounting, this power supply accepts a wide input voltage range of 85 to 264V AC or 110 to 370V DC, accommodating global power standards across 47 to 440Hz frequencies. It delivers three isolated outputs: +5V at 2.0A, +12V at 0.3A, and -12V at 0.2A. The unit achieves up to 75% efficiency and includes comprehensive protection features such as automatic recovery overcurrent protection when exceeding 105% of the rated load.
Electrical performance is maintained with tight line regulation of 20mV on the primary rail and ripple and noise levels kept below 120mVp-p. Safety and compliance are verified through UL60950-1, CSA, EN60950-1, and IEC60950-1 certifications, alongside FCC Class B conducted noise limits. The enclosure provides strong isolation ratings, including 3,000V AC between input and output, and operates reliably within a temperature range of 0°C to +65°C. Its compact mechanical footprint measures 223.0mm in length, 93.0mm in width, and 42.0mm in height, making it suitable for space-constrained control panels and rack-mounted systems requiring stable multi-rail power distribution.
