Note 1: Voltage accuracies are only guaranteed for factory-programmed settings. Changing the output voltage from that reflected in the customer
specific CSIR code might result in inaccuracies exceeding those specified above by 1%.
Note 2: For more accurate active current levels under several load conditions, Summit’s proprietary design software can be used. Contact the
factory for more information.
Note 3: Guaranteed by Design and Characterization – not 100% tested in Production.
