150W AC/DC Supplies Play It Cool

Measuring 5" x 3" x 1.25", the TLP150 series ac/dc power supplies deliver up to 150W of power with low airflow requirements—convection cooling up to 100W, then 200 LFM to 150W. The supplies offer 12V, 24V, or 48V outputs. The 12V model can be used to directly power boards with multiple, non-isolated point-of-load converters, while the 24V and 48V models are suitable for feeding on-board isolated brick or intermediate bus converters. The 24V model is also a contender for powering electromechanical loads. In addition to the main output, each supply provides a 12V output. A third, auxiliary always-on 5V output is available as an option. Shared features of each model includes RoHS compliance, an open-frame design, universal inputs, 81% efficiencies at full load with a 115 Vac input and 84% with a 230 Vac input, plus over-current/voltage, and over-temperature protection. Prices start at $69 each/500. ARTESYN TECHNOLOGIES INC., Framingham, MA. (888) 283-3122.
