SPD3303X/X-E Series Programmable DC Power Supply

Product Overview:

SPD3000X Series Programmable Linear DC Power Supply has a 4.3 inch TFT_LCD display, Supports Programmability and Real Time Wave Display, bringing a new experience to users. It has three isolated outputs: two adjustable channels and one selectable channel from 2.5v, 3.3V, and 5V. It also has output short and overload protect function, and can be used in production and development.


Main Benefits:


  •  3 independent controlled and isolated outputs, 32V/3.2A×2, 2.5V/3.3V/5V/3.2A×1, total 220W
 •  5 digits Voltage, 4 digits Current Display, Minimum Resolution: 1mV/1mA (SPD3303X)
 •   Supports front panel timing output functions

 •  4.3 inch true color TFT- LCD 480x272 display
 •  3 types of output modes: independent, series, parallel

 •  100V/120V/220V/230V compatible design to meet the needs of different power grids.
 •  Intelligent temperature-controlled fan, effectively reducing noise
 •  Clear graphical interface, with the waveform display function
 •  Internal 5 groups of system parameter save/recall, supports data storage space expansion
 •  Provides PC software: Easypower, supports SCPI, LabView


   High-resolution and high-precision output:

The highest 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 functions:

Series and parallel functions 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.

Parallel output mode

 •  Panel displays the timing output:

Through 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.
