The Sorensen SGA80X63C-2GAA is a 5 kW programmable DC power supply engineered for precision testing and production applications. It delivers 0–80 V at 0–63 A with exceptional load transient response, recovering within 1 ms to ±0.75% of steady-state output during 50%–100% load steps. Line regulation holds ±0.01% of full scale in voltage mode and ±0.05% in current mode across ±10% AC input variation. Load regulation maintains ±0.02% voltage mode and ±0.1% current mode from no-load to full-load conditions. The unit achieves 87% efficiency at nominal line and maximum load, with output stability of ±0.05% after 8 hours warm-up. Current ripple stays below ±0.04% RMS in current mode. Analog front-panel controls employ 10-turn potentiometers for voltage and current adjustment, paired with a 3½ digit LED display reading to ±(0.5%fs + 1 digit) accuracy. Over-voltage protection is adjustable and resettable from the front panel. Front air intake enables high-density rack mounting without inter-unit clearance requirements. DC voltage slew rate reaches 100 ms (5–95% full scale), while DC current slew rate delivers 45 A/ms. Temperature coefficients are 0.02%/°C for voltage set point and 0.03%/°C for current set point, both relative to maximum ratings. The output negative terminal floats within ±150 V of chassis potential. Optional passive power factor correction to 0.9 is available.
