Product Introduction

Siglent’s SPD3303X & SPD3303X-E Series Programmable Linear DC Power Supplies have a 4.3 inch TFT-LCD display, support Remote Programming and have Real Time Wave Displays. The SPD3000X Series 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.

Key Features

  • Total Power 220 W
  • 3 independently controlled and isolated outputs
  • 5 digit Voltage/4 digit Current Display, Minimum Resolution: 1 mV/1 mA (SPD3303X)
  • 100 V, 120 V, 220 V and 230 V compatible design.
  • 4.3 inch true color TFT- LCD 480 x 272 display

Product advantage

Excellent Output Performance

The SPD3303X/X-E is robust and stable, and can accurately simulate even small voltage or current changes, fully meeting the power requirements of the load.

· Ultra-high resolution: 1 mV, 1 mA
· Excellent setting and readback accuracy to ensure accurate and pure output
· Support panel programming and timing output
· 3 independently controlled and isolated outputs

Convenient Operation and Real-time Display

Support panel timing output function (5 sets of timing settings and output control). With Free PC software EasyPower, comprehensive communication and control requirements can be easily achieved.

The SPD3303X/X-E programmable linear DC power supply employs a 4.3-inch, 160,000-color TFT-LCD liquid crystal screen with a resolution of 480×272 which can display voltage and current clearly, allowing users to understand the output status.

Series/Parallel/Independent Modes

The series-parallel function combines two power supplies into one power supply, which expands the output power range of a single power supply, which brings convenience in some applications. The three independent power supplies can individually control the output switch, and they can be turned on or off at the same time.
