3.2.9.1
REAL-TIME VOLTAGE/CURRENT ADJUSTMENT
Rotating the associated control will change the output voltage or current in real-time only if the
output is enabled. If the unit is in constant voltage mode (
CV
indicator lit) the
DC VOLTS
display
shows the actual output voltage as the
VOLTAGE
control is rotated. Similarly, if the unit is in
constant current mode (
CC
indicator lit) the
DC AMPERES
display shows the actual output cur-
rent as the
CURRENT
control is rotated.
NOTE: If the unit is in CV mode, rotating the
CURRENT
control will affect the current limit even
though the
DC AMPERES
display does not change since it is showing actual output
current. Similarly, rotating the
VOLTAGE
control while in CC mode affects the voltage
limit. To change the limits to a precise value, refer to PAR. 3.2.9.2, Setpoint Adjust-
ment.
Voltage and current settings are not allowed to exceed either a) the virtual model setting or b)
80% of the protection value. Attempts to set voltage or current beyond these limits will not be
accepted. The status display shows either
>MAX
for virtual model limits,
>OVP
for voltage pro-
tection, or
>OCP
for current protection to indicate which limit is being exceeded.
3.2.9.2
SETPOINT ADJUSTMENT
Tap either the
VOLTAGE
or
CURRENT
control to initiate setpoint adjustment (status display
reads SET). The previous setpoint is visible on the corresponding
DC VOLTS
or
DC AMPERES
display.
1. Rotate the corresponding control to change the setpoint as viewed on the corresponding
LED display. If you decide not to change the setting after rotating the control, the previous
setpoint value is restored after approximately 20 seconds. Tap either adjustment control
again to accept the displayed setting.
2. In the setpoint mode, both coarse and fine adjustment are available (see PAR. 3.2.3 to set
coarse/fine preference). The coarse adjustment is approximately 100X the fine adjustment
resolution.
Setpoint adjust can be done with output either on or off, however the output can not be enabled
while setpoint is active (See PAR. 3.2.5).
Voltage and current settings are not allowed to exceed either a) the virtual model setting or b)
80% of the protection value. Attempts to set voltage or current beyond these limits will not be
accepted. The status display shows either
>MAX
for virtual model,
>OVP
for voltage protection,
or
>OCP
for current protection to indicate which limit is being exceeded. If a fault has been con-
figured for AUTO recovery, the status display flashes
>AUTO
for one second upon leaving Set-
point mode (see PAR 3.2.16.3.2).
3.2.9.3
LAST SETTING RECALL
KLP is capable of saving the last setpoint values for voltage and current prior to unit shutdown,
and recalling them when the unit is next turned on. Enable this function prior to power-up by set-
ting Analog I/O Switch 3 to the ON (down) position (see Table 2-2 and Figure 2-2). Upon next
power-up, each setpoint entry for voltage and current is stored in non-volatile memory, with lat-
est settings displacing prior ones. When the power supply is turned off, the last settings are
saved and automatically retrieved at next power-up as the starting setpoints. Note that this func-
tion applies to setpoint entries only (PAR 3.2.9.2); output changes entered in real-time mode
(PAR 3.2.9.1) are not saved. To disable this function, turn the unit off and set Analog I/O Switch
3 to the OFF (up) position; at next power-up, the stored value buffer is cleared and setpoints will
default to zero volts and minimum current.
