• The maximum sink current at higher voltages will not be the maximum specified current due to the power limit.
For example for an SM66-AR-110 at 30V, the max sink current will be 10 A (30 V x 10 A = 300 W = max power).
•
A higher sink current than the maximum current will cause the output voltage to rise.
