Emerson / Artesyn / Astec LPT43 Power Supply

The Emerson/Artesyn/Astec LPT43 is a triple-output, open-frame power supply engineered for industrial and commercial applications requiring compact, reliable DC conversion. Operating from universal AC input (85-264 VAC) or DC input (120-300 VDC), the unit delivers 40 W under convection cooling or up to 55 W with 30 CFM forced air. The main +5 V output supplies 8 A with remote sense compensation; auxiliary outputs provide ±12 V at 700 mA. Active power factor correction exceeds 0.90, while 70% typical efficiency and integrated EMI filtering minimize power loss and electromagnetic interference. All outputs feature short-circuit and overvoltage protection. The 3" × 5" × 1.1" footprint and sub-1U height accommodate space-constrained installations.
