LPT60 Series

60—80 Watt AC-DC Power Supplies

The LPT60 series of open-frame AC-DC power supplies comprises five triple output models covering standard voltages from -15 V to 24 V. Each model accepts a universal input of 85—264 Vac or 120—300 Vdc. These compact switch-mode power supplies feature main output overvoltage protection and remote sense, with short-circuit protection on all outputs. LPT60 series power supplies provide 60 watts of output power with free air convection cooling, and 80 watts with 30 CFM of forced air. They are suitable for a wide variety of low power industrial applications.
