LPT25 Series

25—40 Watt AC-DC Power Supplies

The LPT25 series of open-frame AC-DC power supplies comprises four triple output models, covering a variety of standard voltages from -15 V to 15 Vdc. Each model accepts a universal input of 85—264 Vac or 127—300 Vdc. These compact switch-mode power supplies feature main output overvoltage protection and remote sense, with short-circuit protection on all outputs. They provide 25 watts of output power with free air convection cooling and 40 watts with 30 CFM of forced air. Less than 1U high, LPT25 series power supplies are suitable for a variety of uses including test and measurement, single-board computers, telecommunications and networking.
