The Sorensen DLM80-7.5 is a 600 W programmable DC power supply for laboratory and industrial applications. It delivers 0–80 VDC at 0–7.5 ADC with exceptional output stability. Zero Voltage Switching (ZVS) technology generates ripple as low as 2.5 mV rms and noise as low as 15 mV p-p—approaching linear supply performance while maintaining high efficiency and fast load transient response. Line regulation holds voltage to 0.005% of Vmax + 2 mV and current to 0.01% of Imax + 2 mA. Load regulation delivers voltage to 0.005% of Vmax + 2 mV and current to 0.02% of Imax + 5 mA. Temperature coefficients are 0.02%/°C for voltage and 0.03%/°C for current. The supply supports remote sensing for precision at the load and includes adjustable overvoltage protection from 5%–110% of Vmax with preview capability, plus overcurrent protection.
