POWER This field is only valid is the MODE is set to CP constant power It sets the power level for the CP mode The constant power mode operation is also determined by the voltage and current limit settings See paragraph 4 6 1 for details IMP STATE Sets output impedance mode Available settings are OFF The output impedance is at its minimum possible value and the supply zero regulates ON The output impedance is maintained at the set level by reducing the output voltage as a function of the load current as needed Note that this function is only available if the DC supply is set to Constant Voltage mode CV LEVEL This field is only valid is the IMP STATE is set to ON It sets the desired output impedance level The available range is a function of the voltage and current ranges of the KDC model used The minimum value is zero mOhm The maximum value can be calculated by dividing the voltage range by 2 times the maximum current of the DC supply model Thus a KDC40 125 would have a maximum programmable impedance of 40 250 0 16 Ohm or 160 mOhm ALC STATE ON OFF The ALC auto level control state setting is only available on models with the FT fast transient option Refer to section 2 13 On all other models this mode is always off When enabled the ALC state regulates the output voltage as long as the DC supply operates in the CV mode This provides load regulation on a par with models without the ET option The ALC
