ML120.241 24V, 5A, SINGLE PHASE INPUT POWER SUPPLY AC 100-120 / 220-240V Auto Select Input Adjustable Output Voltage Efficiency up to 90.4% Compact Design, Width only 72.5mm Full Power between -10°C and +60°C Large International Approval Package Precise Output Overvoltage Protection 3 Year Warranty GENERAL DESCRIPTION SHORT-FORM DATA The MiniLine-2 series covers the lower power requirements in the range from 15W to 120W. These units in their rugged plastic housing and large screw terminals are highly efficient, very compact, easy to install and are extremely reliable. Besides the standard 24V power supplies, many other output voltages are also available as well as units rated down to -40°C. Output voltage Adjustment range Output current More DIN-Rail power supplies in rugged plastic housings can be found in the MiniLine family which is equipped with quick-connect spring-clamp terminals. These units come in power ranges from 25W to 100W and a variety of output voltages. Output power Output ripple Input voltage The supplementary MiniLine-2 redundancy module MLY10.241 allows building of redundant systems or protecting against back-feeding voltages. ORDER NUMBERS The ML120 units are highly immune against electrical disturbances on the mains and 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. Besides the ML120.241, two additional units are available in the ML120 series. The ML120.CLASS2 fulfills the NEC Class 2 requirements and the ML120.244 is a cost optimized regional version for 230V mains voltages.
