描述

The NPT44-M is a triple-output open-frame AC-DC power supply from Artesyn's NPT40-M series, delivering 45 to 55 W of total power with three independent regulated outputs: +5 V, +24 V, and +12 V. It accepts universal input of 90 to 264 VAC or 127 to 300 VDC at 47 to 440 Hz, with an inrush current less than 50 A peak at 230 VAC cold start. The unit features 75% average efficiency, built-in EMI filtering (CISPR 22 Class B), overload and short-circuit protection on all outputs, and operates from 0°C to +80°C ambient with a demonstrated MTBF exceeding 550,000 hours at full load and 25°C. It holds medical and ITE safety approvals (TUV 62368-1, UL 60601-1, CSA 62368-1) and is housed in a compact 2" × 4" footprint less than 1U high, making it ideal for information technology equipment, light industrial systems, and low-power medical, dental, and laboratory applications.
