Siglent SPD4306X Programmable Linear DC Power Supply

Overview

The Siglent SPD4306X is a 4-channel programmable linear DC power supply featuring a compact 3U half-rack package. It delivers CH1 at 15V/1.5A, CH2/CH3 at 30V/6A, and CH4 at 15V/1A with a total rated output of 400W. The supply combines high resolution (1mV/1mA), precision control, and versatile channel configuration options for laboratory and manufacturing applications.

The unit features a 4.3-inch color TFT LCD display with real-time waveform monitoring, multiple communication interfaces (USB and LAN standard), and optional USB GPIB support. An embedded web server enables direct browser-based control without additional software installation.
