SPD4000X Series Data Sheet

Product Overview
The SPD4000X series programmable linear DC power supply is equipped with a 4.3-inch TFT-LCD display, friendly humanmachine 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 to1mV/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 fromproduction 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 ensuresaccurate 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 theapplication range. Each of 4 channels power can be turned on
or off independently or all together.

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

List OperationBy 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-steprunning. Through panel operation, 8 sets of built-in list
sequence output control can be achieved, providing users withsimple power programming capabilities.

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

Powerful Web Control
The power supply includes USB and LAN communication interfaces as standard and a USB-GPIB converter module asoptional. 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 highpressure and high temperature. The embedded virtual control panel is simpler and more convenient to use.
