Atec Sorensen-SG Series - Manual (Page 4)

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-
rent within the power supply single-unit specifica-
tions, with exception of the DC output current 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)
