The time required for the output voltage to change from a specified initial value
to another programmed value, +/-0.1%, does not exceed 20 ms. The allowed
voltage change includes the following worse case conditions:
• Down-programming, at no load, from full-scale output voltage to zero, +/-
0.5% of full-scale
• Up-programming, at full load, from zero to full-scale output voltage
For up-programming, the output voltage ramp speed is proportional to the
programmed value of the output current. To achieve the 20ms ramp time for a
programmed voltage step change from zero to full-scale, and with full output
load, the output current must be programmed to full-scale. To maintain the
20ms ramp time with programmed values of output current at less than full-
scale, the programmed voltage step change must be correspondingly reduced.
