34 KDC Series II DC Power Supplies
ENTRY DESCRIPTION
output voltage returns to its set value.
CP Constant power mode. The supply maintains the
set voltage as long as the power level is below
the set power level. If the power reaches the set
level, the voltage is reduced as needed to
maintain the set power level.
Note: This mode requires firmware revision 1.11 or
higher.
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
–FT option.
The ALC has a maximum adjustment range. If the required
adjustment cannot be made, no fault is generated.
