ML60.121 12V, 4.5A, SINGLE PHASE INPUT POWER SUPPLY 100-240V Wide Range Input NEC Class 2 Compliant Adjustable Output Voltage Efficiency up to 87.2% Low No-load Losses and Excellent Partial-load Efficiency Compact Design, Width only 45mm Full Power between -10°C and +60°C Large International Approval Package 3 Year Warranty GENERAL DESCRIPTION SHORT-FORM DATA A compact size, light weight, simple mounting onto the DIN-rail and the utilization of only quality components are what makes the MiniLine power supplies so easy to use and install within seconds. Output voltage Adjustment range Output current A rugged electrical and mechanical design as well as a high immunity against electrical disturbances on the mains provides reliable output power. This offers superior protection for equipment which is connected to the public mains network or is exposed to a critical industrial environment. Output power Output ripple Input voltage Mains frequency AC Input current Power factor AC Inrush current Efficiency Losses Temperature range Derating Hold-up time Dimensions Weight The MiniLine series offers output voltages from 5 to 56Vdc and a power rating from 15W to 120W. The supplementary MiniLine decoupling diode module MLY10.241 allows building of redundant systems or to protect against back-feeding voltages.
