The Siglent SPD4121X programmable linear DC power supply is equipped with a 4.3-inch TFT-LCD display, a user-friendly man-machine interface, and excellent performance indicators. The real-time waveform display provides engineers with an informative user interface. The SPD4000X series comprises three models with up to four independent outputs, rated at 32 V, 12 V, or 30 V and with a total output power of 240 W, 285 W, or 400 W. The minimum resolution can be set to 1 mV/1 mA.
To prevent damage of the Siglent SPD4121X the device is equipped with overvoltage and overcurrent protection. Together, these capabilities make the Siglent SPD4121X a high-precision, low-noise, and highly reliable power solution suitable for use in production and research. The instrument is also fitted with a LAN/USB communication interface and remote web page control function to meet different application scenarios.
