SIGLENT SPD4000X Series Programmable Linear DC Power Supply Introduction

The SPD4000X series of programmable linear DC power supplies is equipped with a 4.3" TFT-LCD display, friendly human-machine interface, and excellent performance indicators. Real-time waveform display provides engineers with an informative user interface. 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 minimum resolution can be set to 1mV/1mA. 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.

Characteristics:

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.

Series/Parallel/Independent Mode

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.

Real Time Waveform Display

The SPD4000X series of programmable linear DC power supplies is equipped with a 4.3", true color TFT-LCD display screen with a resolution of 480 x 272 pixels. 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 Operation

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.

Save/Recall Settings Parameters

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.

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. 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.
