The Sorensen SGA80-313C-1DDA is a 25 kW programmable DC power supply engineered for precision operation in laboratory, research, and industrial environments. This analog-controlled unit delivers 0–80 VDC at 0–313 ADC with exceptional load transient response and low noise, making it ideal for applications requiring stable, repeatable power delivery. The compact 3U rack-mount chassis combines high power density with straightforward front-panel analog control, supported by optional remote sensing and parallel operation capability.
