Specifications of the Sorensen SGA80/125 include: Common:
Remote Sense: Load-line loss compensation for models <= 100 V is 10% above full scale voltage total (5% per load-line), and models > 100 V is 4% above full scale voltage total (2% per load-line).
Parallel Operation: Up to 5 units may be paralleled for additional cur within the power supply single-unit specifications, with exception of the DC output cur set accuracy. Additional paralleled SG units will add 0.3% inaccuracy per unit. To parallel more than 5 units,contact factory.
Series Operation: Up to 2 units (see Output Float Voltage)

Output:
Ripple & Noise (Voltage Mode, Typical): Ripple and noise specified at full load, nominal AC input. Noise measured with 6ft. cable, 1µf at load
Ripple (Cur Mode): <+/- 0.04% of full scale rms cur
DC Voltage Slew Rate: 45A / ms typical – resistive load
Line Regulation (with sense wires used): (±10% of nominal AC input, constant load); Voltage Mode: +/- 0.01% of full scale; and Cur Mode: +/- 0.05% of full scale
Load Regulation (with sense wires used): no load to full load, nominal AC input); Voltage Mode: +/- 0.02% of full scale; and Cur Mode: +/- 0.1% of full scale
Load Transient Response: Recovers within 1ms to +/-0.75% of full-scale of steadystate output for a 50% to 100% or 100% to 50% load change
Efficiency: 87% typical at nominal line and max load
Stability: ±0.05% of set point after 30 minute warm-up and over 8 hours at fixed line, load and temperature
Temperature Coefficient: 0.02%/ C of maximum output voltage rating for voltage set point 0.03%/ C of maximum output cur rating for cur set point
Output Float Voltage: Negative terminal within +/- 300 V of chassis potential. (We recommend the use of optional isolated analog Interface (IAI).) Supplies in “series” should be the same output voltage/cur.
