The SPD4000X series power supply is an ideal tool for testing devices and can be widely used in power electronics, manufacturing, wireless communications, and consumer electronics applications. The SPD4000X series adds increased power, flexibility, accuracy, and a fourth channel without taking up any extra space to our popular line of Siglent linear DC power supplies.
The SPD4000X supports five-digit voltage and five-digit current display with excellent 1mV/1mA read and set resolution. The four output channels can be controlled independently or simultaneously activated or deactivated. Series and parallel functions allow two channels to be combined into a single output with higher power output capacity. For example, the SPD4306X can output 60V/6A when the outputs are in series, and the SPD4121X can output 12V/20A when the outputs are in parallel. Additionally, channels CH2 and CH3 can utilize the included 4-wire detection mode, which automatically compensates for voltage drop across the positive and negative output lines, ensuring that the voltage at the remote device under test matches the set power supply voltage. It can achieve a maximum voltage compensation of 0.6V for high-precision or long-wire testing. Output response time is the time it takes for the voltage to return to the set range when the load current suddenly changes. The SPD4000X series achieves a fast output response time of <50µs, enabling rapid compensation of output voltage fluctuations.
By editing the single-step adjustment value and duration, the list function can generate multiple sequences to meet complex testing requirements. Users can edit the sequence in 50 steps, with 8 sets of built-in list sequence files. Voltage, current, time, etc., can be adjusted directly in each list, which is excellent for simulating a variety of voltage and current states, such as sudden rises and falls, and interruptions.
For complex waveforms that are difficult to edit, list sequence files can be imported via USB to improve test setup efficiency. List time accuracy of <50 ms, adjustment resolution of 1 ms, along with fast voltage rise/fall times and very short voltage changeover times, can meet the most demanding user requirements for impulse voltage testing.
The SPD4000X series is equipped with a 4.3-inch color TFT-LCD display. Four channels of voltage and current waveform run graphs can be configured; users can observe the waveform run graph using the colors corresponding to the channels to understand the output status of the four channels.
The SPD4000X series allows users to save various types of files to local or external memory for later retrieval. It supports saving output voltage/current values, independent/serial/parallel output modes, and can capture screenshots by long-pressing the Save/Recall key in any state, which is very useful for capturing dynamic test conditions.
The power supply includes serial USB and LAN communication interfaces and an optional USB-GPIB converter module. The integrated web server allows you to control and monitor the power supply directly from a web browser, eliminating the need to install drivers or software applications.
