Siglent SPD4323X – Four Channel DC Power Supply (240W)

• Total output power: 240W
• Channel 1: 6V / 3.2A
• Channel 2: 32V / 3.2A
• Channel 3: 32V / 3.2A
• Channel 4: 6V / 3.2A

The SPD4000X series programmable linear DC power supply is equipped with a 4.3-inch TFT-LCD display, friendly human machine interface, and excellent performance indicators. Real-time waveform display provides engineers with an informative user interface.

The SPD4000X is equipped with overvoltage protection and overcurrent protection for device protection. Together, these capabilities make the SPD4000X a high precision, low noise, and highly reliable power solution suitable for use from production to research. The instrument is also equipped with LAN/USB communication interface and remote web page control function to meet different application scenarios.

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.

Several versions available

The SPD4000X series consists of three models with up to four independent outputs with rated output voltage values of 32V, 12V, or 30V and the total output power of 240W, 285W or 400W.

The chart below outlines several main features of each:

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.

Series and parallel functions allow two channels combined into one output with more power output capability, extending the application range. Each of 4 channels power can be turned on or off independently or all together. Please note, the image below shows the SPD4323X.

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.

By editing the single-step setting value and duration, the list function can generate multiple sequences to meet complex test requirements. The user can edit the sequence by 50 steps natively or import the list sequence file via USB for multi-step running. Through panel operation, 8 sets of built-in list sequence output control can be achieved, providing users with simple power programming capabilities.

The power supply allows users to save multiple types of files to memory for later recall. The power supply provides a nonvolatile internal memory and access to external memory via the USB Host interface on the rear panel. Save setups, settings, and more directly to the supply or to a USB memory stick for transport.

The SPD4000X series includes standard USB and LAN communication interfaces. An optional USB-GPIB converter module is also available. 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. It can meet the application needs of special environments such as high pressure and high temperature. The embedded virtual control panel is simpler and more convenient to use.
