SPD4000X Series Quick Start

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 userinterface 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:

4W Sense Mode
Only CH2 and CH3 can activate 4W sense mode, and 4W sense mode is not supported in series or parallelmode. When 4W sense mode is turned on and the wires are correctly connected, it can automaticallycompensate for the voltage drop of the positive and negative output lines, ensuring that the voltage of theremote 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
