Emerson / Artesyn / Astec LPT42 Power Supply

The Emerson/Artesyn/Astec LPT42 is a 40W open-frame AC-DC power supply designed for ITE (Information Technology Equipment) and medical applications. It features a universal input voltage range and provides three outputs: +5V, +12V, and -12V. This power supply is known for its compact 3″ x 5″ footprint and being less than 1U high, making it suitable for space-constrained designs. It includes features such as remote sense on the main output, short-circuit protection on all outputs, and an adjustable main output.
