Basic Operation

Output Mode Setting

The SPD4000X has four sets of independently adjustable output sources, each output source supports
constant voltage mode and constant current mode. The CH1/CH4 of the SPD4000X have only one
independent output mode, when the CH2/CH3 have three output modes: independent, parallel and series.

In the independent mode, the output current and voltage are controlled respectively. In the parallel mode,
the current value is twice that of the single channel. In the series mode, the voltage value is twice that of
the single channel. When CH2 and CH3 are operating in independent mode, the 4W sense mode can be
activated.

Constant Voltage/Current Mode

The SPD4000X supports constant voltage and constant current mode. If the output load impedance value
is greater than the value obtained by dividing the voltage setting by the current setting, the instrument will
operate in constant voltage mode (CV). If the output load impedance is less than the value obtained by
dividing the voltage setting by the current setting, the instrument will operate in constant current mode (CC).

•

In constant voltage mode, the current value is less than the set value, and the voltage value is controlled
through the front panel. The user interface will display CV logo at this moment, and the voltage value
is maintained at the set value. It will return to constant current mode when the output current value
reaches the set value.

•

In constant current mode, the current value is rated and controlled through the front panel. The user
interface displays the CC logo, and the current is maintained at the set value. At this point, the voltage
value is under rating. It will return to constant voltage mode when the output current value is less than
the set value.

Independent Output Mode

CH1~CH4 are working in the independent mode, at the same time, they are insulated from the ground. The
withstand voltage of the output terminals to the ground is ± 240VDC.

Setting method:

1. Press Configure corresponding menu button on the panel to enter the configure setting interface.

2. Press Independent corresponding menu button on the panel, and the Independent under
Operation Mode of the interface lights up, indicating that independent mode is selected. At this point,
the Parallel/Series button light is off, and there is no serial or parallel logo on the user interface.

3. Connect the load to the terminals on the front panel: CH1 +/-, CH2 +/-, CH3 +/-, CH4 +/-.

4. Set voltage and current value of CH1/CH2/CH3/CH4:

SPD4000X Series Quick Start 13

a) Press 1 / 2 / 3 / 4 button to select the wanted channel
b) Move the cursor through left/right direction button to select the wanted parameter (voltage, current)
c) Use the numeric keypad or knob to set the required value and then press Enter button to

complete the value setting

5. Turn on the output: Press ON button to turn on the output, the corresponding channel indicator light
activates immediately, and "CC" or "CV" logo is shown on the current interface.

CH2/CH3 Parallel Mode

In the parallel mode, the current value is twice as much as the single channel. CH2/3 are linked internally
into one channel which is controlled by CH2, and CH2 reads the parallel voltage and current values.

Setting method:

1. Press Configure corresponding menu button on the panel to enter the configure setting interface.

2. Press Parallel corresponding menu button on the panel to enable CH2/3 parallel mode, and the

range of CH2/CH3 parallel voltage/current values under CH2/3 Parallel light up, indicating that
parallel mode is selected. At this point, the Parallel/Series button light is on, and there is "CH2/3
Parallel" logo on the user interface.

3. Connect the load to the terminals on the front panel: CH2 +/-.

4. Set voltage and current value.
a) Press 2 button to select the channel 2
b) Move the cursor through left/right direction button to select the wanted parameter (voltage, current)
c) Use the numeric keypad or knob to set the required value and press Enter to complete the

value setting

5. Press On button corresponding CH2 to turn on the output.

CH2/CH3 Series Mode

In the series mode, the voltage value is twice compared with that of single channel. CH2/3 are linked
internally into one channel which is controlled by CH2, and CH2 reads the parallel voltage and current
values.

Setting method:

1. Press Configure corresponding menu button on the panel to enter the configure setting interface.

2. Press Series corresponding menu button on the panel to enable CH2/3 series mode, and the range

of CH2/CH3 series voltage/current values under CH2/3 Series light up, indicating that series mode
is selected. At this point, the Parallel/Series button light is on, and there is "CH2/3 Series" logo on
the user interface.

3. Connect the load to the terminals on the front panel: CH2+ & CH3-.

14 SPD4000X Series Quick Start

4. Set voltage and current value.

a) Press 2 button to select the channel 2
b) Move the cursor through left/right direction button to select the wanted parameter (voltage, current)
c) Use the numeric keypad or knob to set the required value and press Enter to complete the

value setting

5. Press On button corresponding CH2 to turn on the output.

Note: Users can also use the Parallel/Series button on the front panel to select independent, parallel, or
series modes directly.

4W Sense Mode

Only CH2 and CH3 can activate 4W sense mode, and 4W sense mode is not supported in series or parallel
mode. When 4W sense mode is turned on and the wires are correctly connected, it can automatically
compensate for the voltage drop of the positive and negative output lines, ensuring that the voltage of the
remote device to be tested is equal to the set voltage of the power supply. To use this function, you need
to use the voltage sense connector in the attachment.

Save and Recall

The SPD4000X supports saving the current settings to native internal storage or an external U disk, users
can recall the saved file to restore the settings. If the external mode is selected, the data will be saved in
the external U disk and can be recalled in the recall mode.

Eight group setups can be saved in memory. The contents of the setup file including:

 Independent/series/parallel mode
 Output voltage/current value

Save/Recall include universal save/recall and list save/recall. The following describes the operation steps
for universal save/recall, with similar steps for list save/recall.
