Cosel PMC30E-2 Switching Power Supply

The Cosel PMC30E-2 is a 33W triple-output AC-DC switching power supply engineered for industrial and commercial equipment requiring compact, convection-cooled power delivery. This open-frame, panel-mount unit accepts universal AC input (85–264V, 47–440Hz) or DC input (110–370V), making it suitable for globally distributed installations. It delivers three regulated DC rails: +5V at 3.0A, +15V at 0.7A, and −15V at 0.5A, with fast startup in 50ms and 20ms hold-up time.
