ARTESYN
LPT40-M SERIES
40 W
Advanced Energy's Artesyn LPT40-M series of open-frame
AC-DC power supplies comprises two triple output models,
covering standard voltages from -15 V to 15 V. Both feature
medical safety approvals, with a very low safety ground
leakage current of less than 75 µA. Each model accepts a
universal input of 85 to 264 VAC or 120 to 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 40 W of output power
with free air convection cooling and 55 W with 30 CFM of
forced air. Less than 1U high, LPT40-M power supplies
are designed for medical, test and measurement, singleboard computers, telecommunications and networking
applications.
