The Emerson/Artesyn/Astec LPQ154 is a 150 W open-frame AC/DC power supply engineered for industrial and commercial applications requiring multi-output regulation and load-sharing capability. This quad-output design delivers 5 VDC, 12 VDC, −12 VDC, and 24 VDC rails with individual load regulation and remote sense on the primary output, making it suitable for distributed power architectures in ITE environments.
