Saelig Company has announced the new Siglent SPD4000X series of four-channel programmable linear DC power supplies that includes three models with output power of 240, 285 or 400 watts, designed for applications such as device testing as well as new energy, manufacturing, wireless communications, consumer electronics, laboratories, education, and more.
All three units offer a minimum resolution of 1mV/1mA on the four independent programmable outputs — two of the channels can be connected in series or in parallel by one-click to output more voltage or current. The SPD4306X can output 60 volts/6 amps in series, and the SPD4121X can output 12 volts/20 amps in parallel.
The four-wire remote voltage sense function allows compensation of up to 0.6 volt to ensure the correct voltage is delivered to a device under test. The SPD4000X series supports a five-digit voltage and five-digit current 4.3-inch color TFT-LCD display, showing a setting and read-back resolution of 1mV/1mA.
The four output channels can be independently controlled and turned on or off simultaneously, and these supplies can be programmed to generate multiple sequences of voltage, current, and time, to meet complex test requirements. Specific sequences can simulate a variety of voltage and current test states, such as sudden rise and fall, brownout, interruption, etc. More complex sequences that are not easy to edit can be imported via USB to quickly improve test efficiency.
The SPD4000X series has an output response time of < 50us to enable fast compensation for output voltage changes. Output response is the change of output voltage when the load current changes dynamically.
The SPD4000X series allows users to save multiple results to local or external memory, and can take a screen shot, which is beneficial for capturing dynamic test conditions. The power supply series includes USB and LAN communication interfaces as standard, with an optional USB-GPIB converter also available. The embedded Web Server enables control and monitoring of the supply directly from a web browser, eliminating the need for software drivers or applications.
