The Lambda/TDK LNS-P-12 is a 15V linear power supply delivering 20W of regulated DC power with exceptional line and load regulation. Built for industrial environments, this convection-cooled unit requires no external heat sinking or forced air cooling. The supply combines low-noise output, high isolation, and comprehensive protection features including automatic current limiting, optional overvoltage protection, and thermal shutdown.
