Features

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

The series and parallel functions enable the combination of two channels into a single output with increased power output capability, thereby expanding the application range. Each of the four channels' power can be individually switched on or off, or collectively controlled.

Real Time Waveform Display

The SPD4000X series programmable linear DC power supply features a 4.3-inch true color TFT-LCD display screen with a resolution of 480 x 272. It offers the capability to set up voltage and current waveform run charts for all four channels, enabling users to intuitively observe dynamic changes in the output state.

List Operation

By adjusting the single-step setting value and duration, the list function can generate multiple sequences to accommodate complex test requirements. Users can edit sequences with up to 50 steps directly or import list sequence files via USB for multi-step execution. With panel operation, users can access 8 sets of built-in list sequence output controls, offering straightforward power programming capabilities.

Speichern/Abrufen von Einstellungsparametern

The power supply enables users to save various types of files to memory for future retrieval. It features a non-volatile internal memory and allows access to external memory via the USB Host interface on the rear panel. Users can save setups, settings, and more directly to the power supply or to a USB memory stick for portability.

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.
