Siglent SPD3303X - Programmable Linear DC Power Supply with 1 mV/1 mA Resolution (3 Channels, 220W)

Siglent’s SPD3000X Series Programmable Linear DC Power Supply has a 4.3” TFT-LCD display, supports Remote Programming and has a Real Time Wave Display. The SPD3000X has three isolated outputs; two adjustable channels and one selectable channel from 2.5 V, 3.3 V, and 5 V. It also has output short and overload protection and can be used in production and development.

High-resolution and high-precision output

The high resolution of 1mV/1mA (SPD3303X), 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 to be 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 front panel operation, 5 groups of timing settings and output control can be displayed, which provides users with a simple power programming function. A connection can also be made with Siglent’s EasyPower PC software providing a full range of communication and control features.
