The Cosel PMC75E-1 is a triple-output enclosed AC/DC converter designed for commercial ITE applications. It delivers +5V at 2A, +12V at 0.3A, and -12V at 0.2A from a universal AC input of 85-264VAC or DC input of 110-370VDC. The converter achieves a typical efficiency of 65% at 100VAC input and 75% nominal efficiency.
Key electrical characteristics include line regulation of 20mV on the +5V output and 48mV on the +12V and -12V outputs. Load regulation is 100mV on the +5V output and 120mV on the +12V and -12V outputs. Ripple and noise are specified at 120mVp-p for the +5V output and 150mVp-p for the +12V and -12V outputs. The converter includes overcurrent protection that activates above 105% of rated output and recovers automatically.
The PMC75E-1 is housed in an enclosed chassis-mount package measuring 223.0mm x 93.0mm x 42.0mm. It operates over a temperature range of 0°C to +65°C with derating and can be stored from -20°C to +75°C. The unit is certified to UL60950-1, CSA C22.2 No.60950-1, EN60950-1, and EN50178, and complies with FCC-B for conducted noise.
The PMC75E-1 provides three outputs: +5V at 2A, +12V at 0.3A, and -12V at 0.2A.
The AC input range is 85-264VAC and the DC input range is 110-370VDC.
The operating temperature range is 0°C to +65°C.
It is approved to UL60950-1, CSA C22.2 No.60950-1, EN60950-1, and EN50178.
Typical efficiency is 65% at 100VAC input and nominal efficiency is 75%.
The isolation voltage between input and output is 3000VAC for 1 minute.
