SPD4121X Overview

The SPD4121X Programmable Linear DC Power Supply features a 3U package with excellent channel density, and offers four channels with ratings of CH1/CH4 at 15 V/1.5 A and CH2/CH3 at 12 V/10 A and a total rated output power of 285 W. It exhibits high resolution and precision, with the finest resolution of 1mV/1mA, ensuring accurate settings and readings even with minimal changes in voltage or current, a feat unattainable by low-resolution supplies.

In terms of versatility, the power supply's series, parallel, and independent modes allow for combining two channels to enhance power output, thereby broadening its application scope. Users can independently manage the power of each channel or synchronize them as needed. In the case of the SPD4121X, its channels when connected in series achieves outputs of 24 V/10 A and in parallel achieves 12 V/20 A. The real-time waveform display, featuring a 4.3-inch true color TFT LCD screen, provides a clear view of voltage and current changes across all four channels, enhancing the user experience by allowing for dynamic monitoring of output states.

The list operation function of the SPD4121X is particularly useful for complex testing scenarios, enabling the creation of multiple sequences through editing of single-step values and durations. With the capacity for 50 native steps or imported sequences via USB, and eight built-in list sequence controls accessible from the panel, the power supply simplifies power programming tasks. Additionally, users can save various file types to the power supply's non-volatile internal memory or to an external USB drive for easy transport and recall.

Lastly, the SPD4121X offers robust web control capabilities. Standard USB and LAN interfaces, along with an optional USB GPIB converter module, facilitate seamless integration into various setups. The embedded web server allows for direct control and monitoring from a web browser, negating the need for additional software, which is particularly advantageous in specialized environments like those with high pressure or temperature. The virtual control panel embedded within the server streamlines the user interface, making it more straightforward and user-friendly. This comprehensive suite of features ensures that the SPD4121X Programmable Linear DC Power Supply is a versatile and precise tool for a wide range of power supply needs.

The SPD4000X Series

The SPD4000X series includes three DC power supply models, each offering up to four separate outputs with maximum voltages of 32V, 12V, or 30V and total power capacities of 240W, 285W, or 400W.
