imum output power at 1200 Watts. Maximum current shown on
DC AMPERES
display is
automatically limited to 1200W maximum.
5. Press
DC OUTPUT
switch to accept virtual model settings. The unit displays
done
, then
resets and repeats the power on sequence (see PAR. 3.2.1).
NOTE: Accepting a new virtual model resets the setpoints to zero Volts and minimum
Amperes, resets the OVP and OCP values and, if DIP switch position 3 is enabled,
clears stored setpoints of voltage and current as described above.
3.2.7
SETTING VOLTAGE OR CURRENT
The
VOLTAGE
and
CURRENT
controls adjust output voltage and current limit, respectively,
when the unit is in constant voltage (CV) mode and adjust voltage limit and output current,
respectively, when the unit is in constant current (CC) mode. The mode (CV or CC) is deter-
mined by the load together with the programmed settings. As long as the voltage across the
load produces a current that is less than the programmed Current setpoint, the unit operates in
CV mode (voltage programmed to voltage setpoint, current limited by current setpoint). If the
load changes to the point that current through the load reaches the current setpoint, the unit
automatically enters CC mode (current programmed to current setpoint, voltage limited by volt-
age setpoint).
Output voltage or current can be set at the front panel in two ways: Real-time adjustment (PAR
3.2.7.1) or Setpoint adjustment (PAR. 3.2.7.2).
3.2.7.1
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. 3.2.7.2, 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.
3.2.7.2
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.
