The range of current limit for both polarities is from 0 to the maximum output, which is 8 A for 54115-24-8 or 12 A for 54130-27-12. The setting resolution for current limit is 1 mA; however, the current won’t be exactly limited down to 1 mA accuracy. 0.1 A error between current limit setting and real current limit can happen. Please note the purpose for current limit is for safety and protection, not for precise current control.
