Common

Remote Sense	Load-line loss compensation for models <= 100V is 10% above full scale voltage total (5% per load-line), and models > 100V is 4% above full scale voltage total (2% per load-line).
Parallel Operation	Up to 5 units may be paralleled for additional current within the power supply single-unit specifications, 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)
