This AC/DC power supply from Cosel, model MMC50A-3-J, is designed as an open frame unit for chassis mounting. It provides three distinct output voltages: +5V, +12V, and -5V, with corresponding maximum currents of 5A, 1.5A, and 0.5A respectively. The total maximum output power is rated at 45.5W.
The converter operates with an efficiency of 70% typical and features a wide input/output type of AC/DC. Its dimensions are 173.0mm in length, 93.0mm in width, and 36.0mm in height. The operating temperature range is from 0°C to 65°C.
Key electrical specifications include a minimum isolation voltage of 2000VAC between input and output. Line regulation for the +5V output is 20mV, while the +12V and -5V outputs have line regulation of 48mV and 20mV respectively. Load regulation for the +5V output is 40mV, for the +12V output is 150mV, and for the -5V output is 100mV. Ripple and noise are specified at a maximum of 120mV for the +5V output and 150mV for the +12V and -5V outputs.
Compliance certifications include cURus and adherence to FCC-B conducted noise standards. The unit is RoHS3 compliant and has an MSL rating of 1.
