ML60.242 24V, 2.5A, SINGLE PHASE INPUT POWER SUPPLY 100-240V Wide Range Input NEC Class 2 Compliant Adjustable Output Voltage Efficiency up to 90.4% Low No-load Losses and Excellent Partial-load Efficiency Compact Design, Width only 45mm Electronic Inrush Current Limitation Operation down to -40°C Full Output Power up to +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 specialty of the ML60.242 is the electronic inrush current limitation and the suitability for very low ambient temperatures. The unit is fully specified down to -40°C. The supplementary MiniLine decoupling diode module MLY10.241 allows building of redundant systems or to protect against back-feeding voltages. ORDER NUMBERS Power Supply Redundancy Module Buffer Module Wall mount bracket Mar. 2013 / Rev. 1.2 DS--ML60.242-EN All parameters are specified at 24V, 2.5A, 230Vac input, 25°C ambient and after a 5 minutes run-in time unless otherwise noted. www.pulspower.com Phone +49 89 9278 0
