The Sorensen DLM40-15 (by AMETEK) is a highly reliable, high-density 600W programmable DC power supply. Housed in a compact 1U, half-rack chassis, it offers continuously variable output voltage (0 to 40 VDC) and current (0 to 15 ADC). It features active power factor correction, dual 3.5-digit LED displays, low output ripple, and versatile analog programming, making it an excellent choice for ATE system integration, benchtop testing, and OEM applications.
