    High-resolution and high-precision output

    The highest resolution of 1mV/1mA, provides excellent setting and read back accuracy. This ensures accurate output even with very with small changes in voltage or current. This is impossible for a low resolution power supply.

    Series/parallel/independent mode function

    Series and parallel function allows two channels combined into one output with more power output capability, extending the application range. Each of 3 channels power can be turned on or off independently and also can be turned all on or all off.

    Panel displays the timing output

    Through the panel operation, 5 groups of timing settings and output control can be displayed, which provides users a simple power programming function. Also a connection can be made with Siglent’s EasyPower PC software providing a full range of communication and control requirements.

    Save/Recall setting parameters

    SPD3000X series programmable power supply can save or recall 5 groups of setting parameter in internal storage, also supports external storage expansion. You can easily obtain the settings you needed.

    Review by Fabien 
    Posted on 16/11/2016
    This power supply is exactly what I was looking for :
    - compact design to keep maximum free space on my desktop
    - very silent, almost no noise at all
    - immediate power on
    - clear screen for setup and use. All is easy to setup quickly.
    - voltage, current and power consumption informations are displayed for each channel.
    - very usefull third power supply channel which generate 3 fixed voltage (2.5V, 3.3V and 5V)
    - accurate output, I buy this version to have 1mV and 1mA accuracy.

    For exemple I have used it to calculate power consumption of my electronic board at different input voltage from 2.5V to 5V with 10mV, it was easy. I haven't try ethernet nor USB connection to drive the power supply from a PC, but I will do it soon, it not seems difficult.

    I am happy it is a high quality product
