The Sorensen SGA160-31C is a 5 kW programmable DC power supply engineered for high-performance industrial and laboratory applications. This analog-controlled unit delivers 160 V at 31 A maximum output, combining precise voltage and current regulation with low noise and exceptional load transient response. The SGA160-31C operates from 3-phase AC input (200–240 V nominal) and features 10-turn potentiometers for manual voltage and current adjustment, backed by a 3½-digit LED readout. Single units scale to 30 kW within a chassis, and multiple chassis can be paralleled to reach 150 kW or higher, making the SG Series adaptable to growing power demands.
