Emerson / Artesyn / Astec LPQ152 150W Power Supply

The Emerson/Artesyn/Astec LPQ152 is a 150W quad-output open-frame AC/DC power supply engineered for industrial and commercial electronic systems requiring multi-voltage rails and precise regulation. This unit delivers 150W with 30 CFM forced air cooling, or 110W convection-cooled, and accepts universal AC input (85–132 VAC or 170–264 VAC auto-ranging) plus 220–300 VDC, operating across 47–63 Hz. Four independently regulated outputs - 5V, 12V, −12V, and a user-adjustable ±5–25V rail - accommodate diverse circuit topologies, with cross-regulation held to ±2% on the main 5V output and ±3% on secondary rails. The unit integrates short-circuit, overload, and overvoltage protection across all outputs, remote inhibit control, power-fail signaling, remote sense compensation, and single-wire current sharing for scalable designs. EMI compliance covers FCC Class B, CISPR 22 Class B, EN55022 Class B, and VDE 0878 Part 3 Class B. Hold-up time reaches 20 ms at 110W load, ensuring stable operation during mains transients. Reverse-connection protected design and comprehensive logic control features simplify integration into safety-critical and high-reliability applications.
