1.8.3 Specific technical data
(1 Related to the nominal values, the accuracy defines the maximum deviation between an adjusted values and the true (actual) value.
Example: a 80 V model has min. 0.3% voltage accuracy, that is 240 mV. When adjusting the voltage to 5 V, the actual value is allowed to differ max. 240 mV, which
means it might be between 4.76 V and 5.24 V.
(2 Typical value at 100% input voltage and 100% power
3) Set values as in the display or as data readable via digital interfaces are more accurate than the corresponding value on the DC input. Their accuracy subtracts
from the general accuracy. For actual values it is vice versa. There the display accuracy adds to the general accuracy, so the error (i.e. deviation) will be higher.
