ML120.CLASS2 24V, 3.8A, SINGLE PHASE INPUT POWER SUPPLY AC 100-120 / 220-240V Auto Select Input NEC CLASS 2 Compliant Efficiency up to 90.4% Compact Design, Width only 72.5mm Full Power between -10°C and +70°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 Output power Output ripple Input voltage 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. Besides the ML120.CLASS2, two additional units are available in the ML120 series. The ML120.241 as the standard 24V, 5A unit (does not conform NEC Class 2) and the ML120.244, which is a cost optimized regional version for 200-240V mains voltages, which is also not NEC Class 2 compliant. ±6% at 120 / 230Vac at 120 / 230Vac peak value at 120/ 230Vac 40°C and cold start DC Input DC 290V -25% / +30% Efficiency 88.8 / 90.4% at 120 / 230Vac Losses 11.5 / 9.7W at 120 / 230Vac Temperature range -10°C to +70°C operational Derating not required +60 to +70°C Hold-up time typ. 70 / 68ms at 120 / 230Vac Dimensions 72.5x75x103mm WxHxD Weight 360g / 0.8lb 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.
