Product Advantage

High-Resolution and High-Precision Output
The highest resolution of 1mV/1mA (SPD4000X), provides excellent setting and read back accuracy. This ensures accurate output even with minimal voltage or current changes. This is impossible for a low-resolution power supply.


Real-time Waveform Display
The SPD4000X series programmable linear DC power supply is equipped with a 4.3-inch, true color TFT-LCD display screen with a resolution of 480×272. 4 channels of voltage and current waveform run chart can be set, allowing users to dynamically observe changes in the output state more intuitively.


LIST Function
By editing the single-step setting value and duration, the list function can generate multiple sequences to meet complex test requirements. Users can edit the sequence by 50 steps, with 8 sets of built-in list sequence files. Voltage, Current, Time, etc. can be set directly in each List, which can be excellent for simulating a variety of voltage and current states such as sudden rise and fall, interruption. For complex waveforms that are not easy to edit, List sequence files can be imported via USB for list output to quickly improve test efficiency. List time accuracy <50 ms，setting resolution 1 ms, with fast voltage rise/fall time and very short voltage change time can meet the user’s fine requirements for pulse voltage testing.


Save/Recall Settings Parameters
The SPD4000X series allows users to save multiple types of files to local or external memory for later recall. It supports saving of output voltage/current values, independent/series/parallel output mode, and can take a screen shot by long pressing the Save/Recall key in any state, which is very beneficial for capturing dynamic test conditions.


Voltage compensation sense function
CH2 and CH3 can use the included 4 wire sense mode, which can automatically compensate for the voltage drop of the positive and negative output lines, ensuring that the voltage at the remote device to be tested is equal to the set voltage of the power supply. It can realize the maximum compensation voltage of 0.6V in high precision test or long cable test.


Powerful Web Control
The power supply includes USB and LAN communication interfaces as standard and a USB-GPIB converter module as optional. The embedded Web Server enables control and monitor of the power supply directly from a web browser, eliminating the need to install software drivers or applications.
